Hi,

I was wondering if it was possible to retry the question untill the right answer is checked ?
I couldn't find anything that could help me with that feature.

Thanks you,
SC.

The validation options are available in many questions types. Look at the advanced option and learn about the ExpressionManager in the manual. You should always state what version of LimeSurvey is used.

Hi,

Thank you for your reply. I did have a look about the validation menue, but i couldn't figure out how to use it the way i want.
Example : Q01 has 2 answers : yes (correct) no (incorrect). What kind of validation would enable me to stay at Q01 if the answer is incorrect ?

The version I am using is 2.72.5+171121

Thanks,
SC.

Take a look at the manual to learn how to access the different variables of different questions.
manual.limesurvey.org/Expression_Manager#Qcode_Variable_Naming

A yes/no question can be accessed via the QCode and Y and N. So {Q1=='Y'} means that a validation is true when Answer to question Q1 is Yes. Such questions are untypical and are mostly just as a first question for consent. If that is the case, you need to check for compliance. If people are stucked in the question they might just close the browser. But than you still have data saved in LimeSurvey, which you might want to prevent.
