Logic not working? Here are 5 ways to fix it

Logic can be tricky to set up. If your form isn’t behaving as expected, use this checklist to find and fix common Logic problems.

1. Check the order of your Logic rules

Logic moves forward through your form. It can’t go back to a question that someone has already skipped.

For example, if a rule sends someone from Question 1 to Question 4, Questions 2 and 3 are skipped. The respondent can’t return to those questions later.

When you add several Logic rules, make sure each rule is based on questions that appear earlier in the form and that the rules are in the correct order.

For more information, see Ordering Logic.

2. Check how you’re using AND and OR

Use AND when all conditions in a rule must be true. Use OR when any one of the conditions can be true.

Don’t combine AND and OR conditions in the same Logic rule. If you need to switch from one operator to the other, create a separate rule instead. This prevents conflicting Logic conditions.

For example:

• Rule 1 (AND): Go to Pricing question when Plan is Business and Number of users is greater than 10.
• Rule 2 (OR): Go to Pricing questions when Plan is Enterprise or Plan is Custom.

Create these as separate rules because the first uses AND and the second uses OR.

3. Having trouble with a score-based personality quiz?

If you’re creating a personality quiz by assigning scores to answers and adding Logic rules, try Match quiz mode instead. It connects answers to different quiz endings and shows respondents the ending that best matches their answers.

For setup instructions, see Create a Match quiz with Typeform.

4. You forgot to set up “reminder” Logic

When multiple selection is enabled and you’re using multi-branching, add “reminder” Logic to the follow-up questions. If you only add Logic to the first question, the follow-up questions won’t remember all the options selected.

In our example, the first question has four answer options, each with its own follow-up question.

Add Logic to the follow-up questions as follows:

1. First, add Logic for each option in the initial Picture Choice or Multiple Choice question.

2. Then, add reminder Logic to each follow-up question:

The first follow-up question needs three reminder Logic rules for all the remaining options.

The second follow-up question needs two reminder Logic rules for the remaining options.

The third follow-up question needs one reminder Logic rule.

The final follow-up question doesn’t need reminder Logic.

This ensures respondents see every relevant follow-up question without seeing the same question twice.

5. Use reverse Logic with blank fields

When you add Logic based on a blank field, use reverse Logic with a negative condition.

For example, use a condition such as is not equal to rather than a positive condition such as is equal to.

You can use negative conditions with blank fields, but positive conditions aren’t supported in the same way. For more information, see How to use reverse Logic with blank fields.
