Conditional logic and calculator features enable you to create dynamic forms that respond to user input in real-time. This guide will walk you through how to use these powerful features to build interactive forms and calculators

What You Can Do with Conditional Logic and Calculators

Show or hide questions based on previous answers
Jump to different pages based on selections
Calculate prices, scores, or other values automatically
Create interactive experiences like quizzes and assessments
Build helpful calculators for loans, pricing, shipping, and more

Access the logic builder

Click on gear icon in the editor header which open a sidebar. There you’ll see two tabs : Form Settings, Variables and Conditional Logic

Understanding variables

Variables are like containers that can store information. They're useful for:

Saving calculation results
Storing temporary values
Referencing values across your form using mentions

To create a variable:

Go to Variables tab
Click on Add button
Give it a name like (total_price or discount_amount )
Click Save

Using Variables and Mentions in Your Form

What Are Mentions?

Mentions allow you to reference variables or field values anywhere in your form using the @ symbol. This creates dynamic content that updates automatically.

How to Add a Mention

To refer to a variable or field in your form:

Type @ in any text field where mentions are supported
A dropdown menu will appear showing available variables and fields
Select the variable or field you want to reference

Example: Using mention to personalize your form

If you collect a user's name in a field called "Name", you can:

Create a welcome message: "Hello @Name, please complete this survey"
Personalize later questions: "Based on your previous answer, @Name, we'd like to know..."
Customize your thank you page: "Thank you @Name for your submission"

Using conditional logic with actions

The logic builder uses an If-Then / Always structure. For eg

IF [Country = USA] THEN [Show shipping options]

Condition Types:

If: Logic runs only when conditions are met
Always: Logic runs regardless of any conditions

Action Types

Go to page

Redirect users to different thank-you pages based on their input. This is useful for personalized user journeys.

Example:

IF [User selects "Interested in Product A"] THEN [Go to Thank You Page A]
IF [User selects "Interested in Product B"] THEN [Go to Thank You Page B]

This allows users to receive a customized thank-you message based on their selections.

Show/Hide blocks

Dynamically display or remove fields and sections based on user input.

To make show block action working, you need to first hide the block by default from field settings and then based on condition you can show the block as shown in video.

Calculate Action

The Calculate action deserves special attention because of its power and complexity. This action allows you to perform mathematical operations and store the results in variables. To check how powerful is calculate action, check out these templates:

What Calculate Does

The Calculate action:

Performs mathematical operations on form values and variables
Stores the result in a target variable
Updates in real-time as users enter information
Can reference other calculated values

Advanced Calculate Features

Chaining Calculations

You can chain multiple calculations to build complex logic:

Calculate a base value
Use that calculated value in another calculation
Create a third calculation that references the second one

This allows you to break down complex formulas into manageable pieces.

Combining with Other Actions

Calculations can be combined with other actions for powerful interactions:

Calculate a value AND show/hide elements based on the result
Calculate scores and jump to different result pages
Calculate pricing and show different payment options
