How logic works

Rules run when someone leaves a screen. Each rule checks conditions and then jumps, shows or hides screens, or changes a score.

Open the Logic tab. Pick a screen in the rail on the left, and its rules appear in the middle. Screens with rules show a branch icon in the rail.

A rule on an NPS question: scores of 9 or more jump to the follow-up for promoters.

What a rule is made of

  • Conditions: what to check, such as an answer, a hidden field, a variable or the device. Join several with AND (all must match) or OR (any can match); click the AND/OR label to switch. A rule with no conditions is an Always rule.
  • Then: one or more actions: Jump to, Skip to the ending, Show screen, Hide screen, Add to, Subtract from or Set a variable.

The order things happen in

  1. When someone leaves a screen, its rules run from top to bottom.
  2. Every matching rule's score and show/hide actions apply.
  3. The first matching jump wins. If nothing jumps, people go to the next visible screen in the list.
  4. Reaching an ending finishes the form. Endings have no rules.

Two ways to add a rule

  • Add rule starts with a condition on the current question (for Yes / No: is Yes) and a jump to the first ending, ready to edit.
  • Add “always” rule has no conditions and adds 1 to score, handy for quizzes.
