i am using the newest version of LimeSurvey Version 2.00+ Build 130122.
In my survey I have a question of type "array numbers (text input)" with checkbox layout and given it the code "X9".
In the subquestions I have entered the possible answer options in the fields for "Y axis", giving them codes from "X9a" to "X9n". In the fields for "X axis" I have entered the two column titles, giving them the codes "X91" and "X92".
The next question, X9a, should only be shown, if someone has chosen the last answer option in question X9. So I have entered X9_X9n_X91=="Y" OR X9_X9n_X92=="Y" as relevance equation in question X9a.
