I have a scenario where I want to create a Multi Choice Question. The MCQ should include subquestions which are union of the selections made in a previous two questions.
PFA the question group file.
The MCQ is with ID Q81b
I want its subquestions of Q81b to be all the selections made in Q16b1 and Q16a. (not just the common selection made in Q16b1 and Q16a)
Currently I am using the array filter Q16b1;Q16a for Q81b which includes only the common selections from Q16b1 and Q16a
Is this possible in Limesurvey 2.05+ version?
