Guide: Conditional Expressions on Questions

Paco provides the ability to show or hide questions based on the responses to other questions. This is like skip logic in some survey tools but it is easier to define complex branching logic in your questionnaires.

Boolean expression about the answer to another, numerically-typed, question

Examples:

• mood == 1
• mood > 3 || location == 2
• mood < 3 && location == 1
