How To: Use Logic in Surveys

Logic within the Ripple surveys can be set at the survey, page or individual question level. You can even group multiple questions together on a panel and set logic for the entire set of questions. When setting logic on pages or questions you can control if the selected page/question should be visible to the participants based on answers to any other question.

All the logic statements can be created or edited on the Survey Logic tab at the top of the survey. These can also be managed under the “Logic” section of the properties panel when editing any component of the survey.
