Hi,

In a questionnaire on drug use I want a follow-up question if the answer to the previous question (checkboxes) is on of a few options and another follow-up question if they reply with another type of drug use.
E.g. if one replies to have used alcohol only, I only want the follow-up questions for alcohol; if one replies to have used nothing, I want them to skip all the follow-up questions and if one replies to have used both alcohol and hard drugs, I want the follow-up questions for both alcohol and hard-drugs. 

I think something goes wrong with the "/ skip=[checkboxes.ZRM11middelen.response!="..alcohol gedronken."], and mainly the != part (the skip ..== script goes perfectly), but I can't see what. 

I attached some of the questions and the surveypage script. 

Hopefully someone can help me out! Thanks!
