I'm creating an "Employment Status" multiple-choice question.
The choices are:
□ Retired
□ Part-time work
□ Full-time work
□ Student
How can I make it possible for a person to choose
[PT work & student]
or
[FT work & student]
BUT prevent choosing [both PT work & FT work]?
UPDATE: On IRC/Chat, c_schmitz said (Sept 27, 2012, 4:30 am Eastern Time):
I would not know of an immediate solution rather than to split it to different questions using conditions
I then said:
c_schmitz: ok. Maybe we'll see this in the next version of LimeSurvey?

unlikely

you can use the expression manager to check both answers and set a question validation equation which shows a meaningsful error message when these two are selected
I asked Mazi:
oh, okay. Is there a newbie-friendly way to implement this idea?
Mazi said
the last example here shows how to use custom question validation:
