Conditional Logic, Calculator, and Variable Mentions

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

Access the logic builder

Click on calculator icon in the toolbar which open a dialog box. There you’ll see two tabs : Variables and Conditional Logic.

Understanding variables

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

To create a variable:

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:

Example: Using mention to personalize your form

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

Using conditional logic with actions

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

Condition Types:

Action Types

Go to page

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

Example:

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:

Below is the video on how to create a simple BMI calculator.

As you can see it’s very to create calculator form. Also I added two two variables to ease the calculation.

Advanced Calculate Features

Chaining Calculations

You can chain multiple calculations to build complex logic:

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:
