What is Conditional Logic?

Conditional logic allows you to:
  • Show or hide questions based on previous answers
  • Skip irrelevant questions
  • Create branching paths through your form
  • Jump to specific questions
  • End the form early based on responses
Example: 
Q1: Do you own a car?
    → Yes → Show Q2: What type of car?
    → No → Skip to Q5

​
Accessing Logic Settings

  1. Open your form in the Form Builder
  2. Click the “Logic” tab in top navigation
  3. View and manage all logic rules

​
Understanding Logic Rules

Each logic rule has two parts:

​
IF (Condition)

Format: IF [Question] [Operator] [Value] Example: IF “Do you own a car?” equals “Yes”

​
THEN (Action)

Format: THEN [Action] [Target] Example: THEN Show Question “What type of car?” Complete Rule: 
IF "Do you own a car?" equals "Yes"
THEN Show Question "What type of car?"

​
Creating Logic Rules

​
Step 1: Add Rule

  1. Go to Logic tab
  2. Click “Add Logic Rule” button
  3. New blank rule appears

​
Step 2: Set Condition (IF)

Select Question:
  • Choose which question to check
  • Dropdown shows all your form questions
  • Example: “Do you own a car?”
Select Operator: Available operators depend on question type: Text Fields:
  • equals - Exact match
  • not equals - Doesn’t match
  • contains - Includes text
  • starts with - Begins with text
  • ends with - Ends with text
  • is empty - No answer provided
  • is not empty - Any answer provided
Choice Fields (Multiple Choice, Dropdown):
  • equals - Selected specific option
  • not equals - Didn’t select option
  • is empty - Nothing selected
  • is not empty - Any option selected
Checkboxes:
  • contains - Includes specific option
  • not contains - Doesn’t include option
  • is empty - Nothing checked
  • is not empty - Any option checked
Number Fields:
  • equals - Exact number
  • not equals - Different number
  • greater than - Number > value
  • less than - Number < value
  • greater than or equal - Number ≥ value
  • less than or equal - Number ≤ value
  • is empty - No number entered
  • is not empty - Any number entered
Date/Time Fields:
  • equals - Same date/time
  • not equals - Different date/time
  • after - Later than date/time
  • before - Earlier than date/time
  • is empty - No date selected
  • is not empty - Any date selected
Yes/No Field:
  • equals - Yes or No
  • not equals - Opposite choice
Enter Value:
  • Type the value to compare against
  • For choice fields: Select from dropdown
  • For text: Type expected answer
  • For numbers: Enter numeric value
  • For dates: Pick from calendar
  • Skip for “is empty” / “is not empty” operators

​
Step 3: Set Action (THEN)

Choose what happens when condition is true: Jump to Question
  • Skip to specific question
  • Bypasses questions in between
  • Useful for conditional paths
  • Example: Skip payment if free plan selected
Show Question
  • Reveal previously hidden question
  • Question appears in form
  • Used with “Hide Question” actions
  • Example: Show “Other” text field when “Other” is selected
Hide Question
  • Conceal question from respondent
  • Question won’t appear in form
  • Can’t be answered
  • Example: Hide company questions for personal users
End Form
  • Complete form immediately
  • Show thank you page
  • No more questions shown
  • Example: End early if not qualified
Select Target Question:
  • For Jump/Show/Hide actions
  • Dropdown lists all questions
  • Choose which question to affect

​
Step 4: Save Rule

  • Rules auto-save as you configure
  • Look for “Saved” indicator
  • Rule is immediately active

​
Logic Rule Examples

​
Example 1: Simple Branching

Goal: Ask about employment only if currently employed 
IF "Are you employed?" equals "Yes"
THEN Show Question "What is your job title?"
Setup:
  1. Create “Are you employed?” (Yes/No field)
  2. Create “What is your job title?” (Short Text)
  3. Add logic rule:
    • IF: Are you employed?
    • Operator: equals
    • Value: Yes
    • Action: Show Question
    • Target: What is your job title?

​
Example 2: Skip Irrelevant Questions

Goal: Skip payment questions for free plan users 
IF "Select your plan" equals "Free"
THEN Jump to Question "Thank you page"
Setup:
  1. Create plan selection (Dropdown)
  2. Create payment questions (Q10-Q15)
  3. Create thank you text (Q16)
  4. Add logic rule:
    • IF: Select your plan
    • Operator: equals
    • Value: Free
    • Action: Jump to Question
    • Target: Q16 (Thank you)

​
Example 3: Conditional Text Input

Goal: Show “Other” text field when “Other” is selected 
IF "How did you hear about us?" equals "Other"
THEN Show Question "Please specify"
Setup:
  1. Create multiple choice: “How did you hear about us?”
    • Options: Google, Social Media, Friend, Other
  2. Create short text: “Please specify”
  3. Add logic rule:
    • IF: How did you hear about us?
    • Operator: equals
    • Value: Other
    • Action: Show Question
    • Target: Please specify

​
Example 4: Early Form Exit

Goal: End form for users outside target region 
IF "What country are you from?" not equals "United States"
THEN End Form
Setup:
  1. Create dropdown: “What country are you from?”
  2. Add logic rule:
    • IF: What country are you from?
    • Operator: not equals
    • Value: United States
    • Action: End Form
    • Target: (none - form ends)

​
Example 5: Number-Based Logic

Goal: Show discount code for large orders 
IF "Quantity" greater than 10
THEN Show Question "Bulk Discount Code"
Setup:
  1. Create number field: “Quantity”
  2. Create short text: “Bulk Discount Code”
  3. Add logic rule:
    • IF: Quantity
    • Operator: greater than
    • Value: 10
    • Action: Show Question
    • Target: Bulk Discount Code

​
Example 6: Multiple Checkboxes

Goal: Show follow-up if specific interest checked 
IF "Interests" contains "Web Development"
THEN Show Question "What programming languages?"
Setup:
  1. Create checkboxes: “Interests”
    • Options: Web Development, Mobile Apps, Data Science, Design
  2. Create checkboxes: “What programming languages?”
  3. Add logic rule:
    • IF: Interests
    • Operator: contains
    • Value: Web Development
    • Action: Show Question
    • Target: What programming languages?

​
Multiple Logic Rules

You can add multiple rules to create complex logic:

​
Rule Priority

Rules execute in order:
  1. First rule (top) evaluates first
  2. Second rule evaluates next
  3. And so on…
Important: First matching rule wins

​
Combining Rules

Example: Age-Based Branching 
Rule 1:
IF "What is your age?" less than 18
THEN Jump to Question "Parental Consent"

Rule 2:
IF "What is your age?" greater than or equal 65
THEN Jump to Question "Senior Discount"

Rule 3:
IF "What is your age?" greater than or equal 18
THEN Jump to Question "Standard Questions"

​
Rule Conflicts

What happens:
  • Only first matching rule executes
  • Subsequent rules ignored for that question
  • Be specific with conditions to avoid conflicts
Best Practice:
  • Order rules from most specific to least specific
  • Test thoroughly
  • Use “Preview” to verify logic works

​
Managing Logic Rules

​
Editing Rules

  1. Find rule in Logic tab
  2. Click on any dropdown to change
  3. Auto-saves on change

​
Deleting Rules

  1. Find rule to delete
  2. Click trash icon (🗑️) on right
  3. Confirm deletion
  4. Rule removed immediately

​
Testing Rules

Preview Mode:
  1. Click “Preview” button in form builder
  2. Fill out form as respondent
  3. Verify logic triggers correctly
  4. Check questions show/hide as expected
Tips for Testing:
  • Test all possible paths
  • Try each conditional branch
  • Verify hidden questions stay hidden
  • Check “Jump to” works correctly

​
Logic with Different Field Types

​
Text Fields (Short Text, Long Text, Email)

Best Operators:
  • equals - Exact match (case-sensitive)
  • contains - Partial match (e.g., email domain)
  • is not empty - Any text entered
Example: 
IF Email contains "@company.com"
THEN Show Question "Employee ID"

​
Choice Fields (Multiple Choice, Dropdown)

Best Operators:
  • equals - Specific option selected
  • not equals - Different option selected
Example: 
IF "Plan Type" equals "Premium"
THEN Show Question "Premium Features"

​
Checkboxes

Best Operators:
  • contains - Specific option checked
  • is not empty - Any option checked
Example: 
IF "Features Needed" contains "API Access"
THEN Show Question "API Usage Estimate"

​
Number Fields

Best Operators:
  • greater than / less than - Range checks
  • equals - Specific value
Example: 
IF "Team Size" greater than 50
THEN Show Question "Enterprise Contact"

​
Date Fields

Best Operators:
  • after / before - Date comparisons
  • equals - Specific date
Example: 
IF "Event Date" after "2024-12-31"
THEN Show Question "2025 Pricing"

​
Yes/No Fields

Best Operators:
  • equals - Yes or No
Example: 
IF "Need Invoice?" equals "Yes"
THEN Show Question "Billing Address"

​
Rating & Opinion Scale

Best Operators:
  • greater than / less than - Score ranges
  • equals - Specific rating
Example: 
IF "Satisfaction Rating" less than 3
THEN Show Question "What went wrong?"

​
Advanced Logic Patterns

​
Progressive Disclosure

Show questions one section at a time: 
Section 1: Basic Info (Q1-Q3)
IF Q3 completed
THEN Show Section 2: Details (Q4-Q6)

IF Q6 completed
THEN Show Section 3: Preferences (Q7-Q9)

​
Qualification Logic

Filter respondents early: 
IF "Are you 18 or older?" equals "No"
THEN End Form (with message: "Must be 18+")

IF "Country" not equals "USA"
THEN End Form (with message: "US residents only")

​
Smart Defaults

Show relevant follow-ups: 
IF "Current Customer?" equals "Yes"
THEN Show Question "Customer ID"

IF "Current Customer?" equals "No"
THEN Show Question "How did you hear about us?"

​
Limitations & Constraints

​
What Logic Can Do

✅ Show/hide questions based on answers ✅ Jump to specific questions ✅ End form early ✅ Create branching paths ✅ Filter respondents

​
What Logic Cannot Do

❌ Change question text dynamically ❌ Calculate values (use form calculations instead) ❌ Validate across multiple questions (use required fields) ❌ Send different emails based on answers (use integrations) ❌ Show/hide based on external data

​
Technical Limits

  • Rules per form: Unlimited
  • Rules per question: Unlimited
  • Nested logic: Supported (rules can trigger other rules)
  • Execution: Real-time on client side

​
Best Practices

​
Design Tips

Do:
  • Keep logic simple and clear
  • Test all possible paths
  • Use descriptive question titles
  • Preview before publishing
  • Document complex logic
Don’t:
  • Create circular logic (A shows B, B shows A)
  • Make too many nested rules (confusing)
  • Rely on text matches (use choice fields instead)
  • Forget to test with real data

​
Performance

Do:
  • Limit rules per form (< 50 recommended)
  • Use “Jump to” instead of multiple “Show/Hide”
  • Group related questions
Don’t:
  • Add unnecessary rules
  • Create redundant conditions
  • Use logic for every question

​
User Experience

Do:
  • Show progress bar for long forms
  • Explain why questions are shown/hidden
  • Provide clear option labels
  • Test on mobile devices
Don’t:
  • Hide required questions (can’t submit)
  • Create confusing paths
  • Use logic to trick users
  • Make form too complex

​
Troubleshooting

​
”Rule not triggering”

Problem: Logic rule doesn’t work Solution:
  • Check condition operator is correct
  • Verify value matches exactly (case-sensitive)
  • Ensure target question exists
  • Test in preview mode
  • Check for conflicting rules

​
”Hidden question still shows”

Problem: Question should be hidden but appears Solution:
  • Verify rule action is “Hide Question”
  • Check condition is actually true
  • Look for conflicting “Show Question” rules
  • Refresh form preview

​
”Jump to not working”

Problem: Form doesn’t jump to target question Solution:
  • Ensure target question exists and is after current
  • Check you’re not jumping backwards (not supported)
  • Verify condition is met
  • Test with different answers

​
”Logic works in preview but not live”

Problem: Logic doesn’t work on published form Solution:
  • Republish form after adding logic
  • Clear browser cache
  • Check form version is latest
  • Verify rules are saved
