I have a question with two subquestions. The answer to these two sub-questions must be an exact numbers.
Suppose that the questions are:
Q001 How much is 2+2?
Q002 How much is 2+3?
I want participants not to be able to progress in the survey if they get at least one answer wrong.
I am writing in the Subquestion Validation Equation Q001 == "4" && Q002 == "5", but apparently it is not working.
Maybe I am getting the validation expression wrong?
