I'd like to use quota control with a multi-response-checkbox. I have to have a specific number of participants who DON'T choose one of the possible response options.
When I type in the logic "Q1<>11", the program tells me that the operator "<>" requires the same types on both sides and that the one on the right is a string instead of a numeric - although it isn't (or at least I don't think it is).
The quota control does work with single response items, though...
How can I solve the problem? What am I doing wrong?
Thank you very, very much!
