Hi there,
i hope, my title is good enought, that everybody can guess, what it means.

I want to have multiple choice answers, for example:

"What kind of job do you have?"
-i love it
-i don't have much to do
-i don't like my job
-Do you know, what I am doing???
-May i work twice?

So multiple choice is no problem, I choosed to make a group and there i made 5 Fields with check button. So now everybody can check or uncheck it, as many he wants. BUT: How can i say, i want minimum one field of those 5 checked? One mandatory field out of five?

I hope you can understand my problem.
