What is page expression and how to configure it?

Page Expression feature in GoSurvey allows the user to set validation for any expression of input data as mentioned in the questionnaire, and move along the question flow.

Used in scenarios which are to be made sure that, if one or more conditions are fulfilled, then only it should move on to the next page.

Example - To make sure the sum of two values or more entered by a respondent is equal to 100, then only it fulfils the condition to move forward to the next page - for that a page expression can be set up accordingly.
