I'm not sure what I'm doing wrong here. I have this quiz with multiple question. The idea is to check that for every group at least one radio button is checked.
The problem is that this only seems to work when none of the radio buttons are checked at all. Then it shows the alert box with 1,2,3 is empty. But when you then select one answer for one of the question, and resubmit it, no alert box shows up at all. Even though 2 groups are still without an answer? Any idea why this is?
