"..alcohol gedronken." (note the dot at the end) is not the response in <checkboxes ZRM11middelen>. The response is "..alcohol gedronken" _without_ any dot at the end:

< checkboxes ZRM11middelen>
/caption = "De volgende stellingen gaan over middelengebruik. In de afgelopen 30 dagen heb ik..: (U mag hier meerdere antwoorden kiezen)"
/ options = ("..alcohol gedronken", "..sigaretten gerookt",
, "..harddrugs gebruikt","..softdrugs gebruikt","..gegokt","..geen van bovenstaande middelen gebruikt. Ik heb ook niet gegokt.")
/orientation = vertical
/required = true
</ checkboxes >

I.e.

/ skip=[checkboxes.ZRM11middelen.response!="..alcohol gedronken."]

cannot work, it needs to read

/ skip=[checkboxes.ZRM11middelen.response!="..alcohol gedronken"]

thanks for the quick reply! that was a fairly stupid mistake...

however, if multiple checkboxes are ticked the follow-up questions do not show up either. (e.g. if alcohol only has been selected, the alcohol follow-up question does appear, but if alcohol and harddrugs have been selected no follow-up questions appear at all)

Also, the follow-up question which drug has been used does not appear:

/ skip=[checkboxes.ZRM11middelen.response!="..softdrugs gebruikt" ||
checkboxes.ZRM11middelen.response!="..harddrugs gebruikt"]

If you need to check for multiple options, the proper syntax would be

<checkboxes mycb>
/ options = ("a", "b", "c")
</checkboxes>

<surveypage mypage>
/ questions = [1=mycb]
</surveypage>

<surveypage a_or_b>
/ skip = [
    !checkboxes.mycb.selected.1 && !checkboxes.mycb.selected.2
]
/ caption = "you should only see this if you selected a or b"
</surveypage>

<block myblock>
/ trials = [1=mypage; 2=a_or_b]
</block>

Hi Dave,

thanks for all the help!

Most of the syntax works fine now. Only one thing puzzles me; I have several different follow-up questions following different responses. Most of the time it works fine, but some (??) of the combinations don't always work.

e.g. when someone answers to type of drugs used, both alcohol AND softdrugs, the softdrugs follow-up questions does appear, but the alcohol questions does not. However, in exactly the same situations but when alcohol and harddrugs are selected, both the alcohol and harddrugs follow-up questions appear correctly. The harddrugs and softdrugs follow-up question always appear when they need to, it's the alcohol question which sometimes does and sometimes doesn't appear, depending on the combination with which other drugs is selected as well. I tried different combinations to find out where it goes wrong; with all types selected it doesn't appear, also it doesn't with alcohol, softdrugs, harddrugs and sigarettes selected, and neither with alcohol and softdrugs selected. However, in alcohol in combination with harddrugs only, or with sigarettes only, or in combination with sigarettes and softdrugs it does appear. 

I attached the parts in the script on the types of drugs and the follow-up questions. 

 I hope you can help me figure out why some combinations work to show the correct follow-up questions and other combinations don't!  

thanks in advance!

Please reference the questions and options you are referring to by name exactly as they are called in the script. Also, please attach code that is actually runnable. It's not possible for me to determine when what surveypage is actually supposed to be run from the code you attached.

With that said, I am unable to reproduce this

"with all types selected it [the alcohol follow-up] doesn't appear"

when putting the code you attached into an executable form (i.e. adding a block that actually runs the pages). See the attached script and data file.

So please provide an actually executable script that exhibits the issue for you and a data file that illustrates it. Thanks!
