Adding the invisible: y
tag to a survey question hides it from the respondent view.
In the example above, the survey variable Q3TOTAL is used to calculate the sum of the three rows from Q3 and then used in the question text of Q4. Q3TOTAL does not display to respondents due to the inclusion of the invisible: y
tag.
Note: A question with an invisible: y
tag is different than a type: hidden
question because invisible questions do not generate HTML, and will not force a page to display if no other content is visible. A type: hidden
question, on the other hand, does create HTML.
