a survey is starting on Monday and I'm in big trouble. I'm working on a huge questionnaire and probably I won't make it. I'll explain it to you.
So that: if Q1=1 then show only W and X
if Q1=2 then show only Y and Z
I know I can do it by splitting Q2 in two questions (Q2_1 with W and X and Q2_2 with Y and Z items, but remember I'm just summarizing the problem: I have tons of items and tons of possible combinations )
Meanwhile, I managed to get the first part of my questionnaire. I tested it, but one group isn't working properly: I answer to all the questions, then I push Forward (or Next, I'm from Italy I don't know how it's written in the English version ) but...what the heck! It says that I didn't answer to all the questions!? I go back and check from the beginning and I find that some mandatory questions, though all the conditions are verified, HAVE BEEN SKIPPED and only by pushing next they're appearing
