The survey I'm constructing is essentially four surveys in one -- I've built in an equation question with a random output, and depending on the output the user is directed to one of four sets of questions. This is accomplished by keeping the other 3/4 of the survey hidden.

Here's where I run into a problem: three out of the four sets of questions are hidden from the user, like I said. However, I want the one set of questions that they see to be mandatory. When I make the questions mandatory, you only see the one question you're supposed to see. So far so good. But then, when you attempt to move on to the next page, it gives the "didn't answer mandatory questions" error. It does this several times, cycling through all the (supposedly) hidden questions and forcing the user to answer all of them, even though they're supposed to remain hidden.

Here's another thing: this only happens with Array questions. Others, like multiple-choice, don't require the user to answer the mandatory hidden questions. They just move along to the next page, no problem.

Any ideas what's going on here? For research design reasons, I really need to the users to answer all questions (that is, all of the questions that they see). But my survey only works if I make the Array questions non-mandatory.

OK, here a few questions:
- What version of LS do you use?
- How do you hide the questions? (Relevance equation? conditions?)

Using 2.06+ build 150730
The hidden questions were made using conditions.

Which template are you using? If it is a non-standard template, what happens when you switch to a standard template?

Usually, the questions hidden by conditions / relevance equations should not cause this problem.

Is it possible to upload the questionnaire as an example for us to test?
