Excluding and Including Questions With Masking

Question masking is used to dynamically exclude and include questions in surveys. If you want to dynamically exclude a question, use this field to create a JScript or JavaScript expression that evaluates to a Boolean value (true or false), as when you create a condition (go to Building a Condition for more information). If the JavaScript expression is evaluated to ‘true’ the question is displayed; if it is evaluated to ‘false’ the question is not displayed. If you leave the field empty, the question is always displayed.
