Additive filter based on a multiple choice question was created by izumi
Hi everyone,
I would like to create a filter for Question2: The question should only be asked if more than one option was selected for Question1.
Question1 is a matrix variable where respondents can choose between "does apply" and "does not apply" for multiple sub-questions.
Question2 should only be directed at those respondents who selected "does apply" at least twice for any of the sub-questions.
Thank you for your help!
Best wishes,
Izumi

countif("apply",that.Question1.NAOK)

where apply is the code for "does apply"

Sorry, but I had to change the question type to "Multiple choice" of Question1 and now it does not work any mroe. I am unable to figure out how to adapt the equation.
The overview of previous questions to Question2 has the following structure with pdwrkXXX being Question1:
pdwrkXXX:[Group of checkboxes] .....
pdwrkXXX:SQ008:[Other][Single Checkbox]...
pdwrkXXX:SQ007:[....][Single Checkbox]...
etc.
The predefined answers for pdwrkXXX are the codes for the sub-questions such as SQ008 or SQ007.
The predefined answers for the sub-questions such as pdwrkXXX:SQ008 are Y(checked) and (not checked).

If you only want to show Q2 if Q1 has at least 2 checked boxes, use something like this:

Code:
count(that.Q1) > 1
