Yeah I know a bit about this exclusiongroupthingy... the problem is making them mandatory...
The problem gets worse since I don't know if the fields (and error-messages) will react in all versions of adobereader the same way.
(There the problem began to begin with... the borders of mandatory radiobuttons appear in older versions in another way than in newer versions of adobereader.)
I made a new thread for this... only thought if I'd be lucky ppl could answer here, because it's both about those checkboxgroups......
Then how to select only one?
