Last updated on Dec 20, 2025

This article will help you understand what “logic” is in Yay! Forms and how it enables dynamic, personalized form experiences. You’ll learn what logic can be used for and how to set up rules, conditions, and actions so your form adapts based on each user’s answers.

What is logic in Yay! Forms?

Logic in Yay! Forms allows you to create dynamic, intelligent forms that adapt based on the user’s answers.
With it, you can:

  • Perform lead scoring and lead qualification.
  • Show or hide questions;
  • Send the user to different sections;
  • Create quizzes, assessments, and personalized question flows;
  • Add up points and automatically display final results.

👉 In practice, this means each user will have a personalized experience, answering only what makes sense for their profile or context.

Video lesson

Before we begin, we have a video lesson explaining, step by step, the content of this file, in case you want to check it out.

How to add logic to the form

1. Access the form

Open the form you want and select the question you want to use as the trigger for the logic.

2. Go to the “Logic” tab

On the right side of the screen, click “Logic”.
Within the tab, press the “Add Rule” button.

3. Define a condition

For example:
IF (your question) = Option A → THEN go to (end screen 1).
IF (your question) = Option B → THEN go to (end screen 2).

👉 Practical example: when creating a DISC profile quiz, each answer adds points to a variable (such as “Dominance” or “Steadiness”) and, at the end, the logic automatically shows the participant’s profile.

Another possible feature is adding one or more conditions by clicking on "+ condition".

4. Add multiple conditions

You can add conditions with AND and OR.
Example:

  • IF (your question) = Option A → go to end screen
    OR
  • IF (your question) = Option B → go to another screen.

5. Add extra actions

You can create as many actions as you want for the same rule.
Example:

  • IF (your question) = Option A → go to end screen and add 10 points to the variable score.

👉 Practical example: in knowledge assessments, each answer can add or subtract points. In the end, the logic displays the result adapted to the user’s performance.

6. Types of conditions and actions available

Depending on the question type, you can configure conditions such as:

  • “is”, “is not”, “contains”, “does not contain”,
  • “starts with”, “ends with”,
  • “is empty”, “is not empty”,
  • “is greater than”, “is less than”, etc.

And actions such as:

  • “Go to”,
  • “Add”, “Subtract”, “Multiply”, “Divide”.
