Hello,

I'm trying to test for a non-existing variable... if a question hasn't been asked yet I get an error message saying "non defined variable" in the Expression Manager, however, I would like to know if the survey participant answered a certain question and show it in an overview (via the question type: text display).

Thanks for any suggestion!
Anja
