Hi all,

I have a group-by-group survey with 10 questions per group.
The questions of either group have the same Randomization group (e.g. RandGroup1, RandGroup2, ...) to randomize the order of questions presented to the participants. All working fine.

However, we will have cases in which the participants shall be presented a non-randomized survey.

My general idea was:
* add an attribute ("rand") to get the information randomization "on" or "off"
* put curly braces around the randomization group name and write something like {if(rand == "on", RandGroup1, "")}

however, it quickly became clear that the Randomization Group field does not work with curly braces and functions. or was I missing something?

I'm hoping for ideas on this issue
Best

No, you cannot use Expression Manager in the randomization group name. My only suggestion would be to copy the survey.

Thanks for the quick answer, @tpartner - I was afraid that this is the only way... but at least now I know for sure

... unless anyone else has a genius idea, of course

Even with 4 and new plugins event to update order of questions (for example) i didn't have an idea on how to do this ....

Order of questions are done before all expression happen , here you want to redo it after ... really complex system.

Thanks for looking into this!

I have one last idea that could work within the same survey. I'll try to illustrate it with a short example.

Group 1: group relevance "rand == yes"
All questions in same randomization group
question1.1: blabla
question 1.2 blublu
question 1.3 bloblo

Group 2: group relevance "rand == no", questions without randomization
question 2.1: blabla
question 2.2 blublu
question 2.3 bloblo

Group 3: always hidden
equation1: if 1.1 != empty, take 1.1, else take 2.1
equation 2:...
equation 3:...

It basically uses the same survey with the double length, instead of dealing with two surveys, so it's not really elegant
Could it work? I currently don't have a computer to try it, so I'd love to get your feedback

? You kidding or you are serious ...

@Niels : yes, it can work if your survey are not too big .

You can put if needed condition on each question.
