Mazi your solution works very well. I put the same condition in all questions of the same group of question, and when it don´t satisfied the survey skips that group of question.
Before of that, I tried to put all of question in the same group of question but the limesurvey had problem when I tried to activate the survey. The size of the database was so large for him.
obs: I´m testing the survey and appears the following message "Session expired". I tried this solution:
bugs.limesurvey.org/view.php?id=5173 but my version (1.91+ Build 10951) already has this modification.
