I thik this is a simple task, but I could not find a solution in the manual, even in EM examples. I have an agree/disagree array, set as a semantic diferencial question with a ten point scale, where 1 is strongly disagree and 10 is strongly agree. So, one of the questions is:
8 times 5 equals 45
.
If the answer is right, i.e., "1 - Strongly disagree", the respondent can go further with the survey. Otherwise, cannot, until he/she provides the right answer. It's like a "pay attention" step.
Each array question is setup as a different variable, meaning that each one is tottaly independent by itself and can be taillored without affecting the rest of the group.
Thanks in advance to who helps me.
Helvio.
