I want to choose only one item of the radio button group, but if another button is set on option have to be set to readonly. Is this simple to build with checkboxes?
Sorry, but my english is not so good.
The only way it's possible with check-boxes is if you use a set of fields that uncheck the other boxes when a box is checked. It's not a simple process, and not one that can be done in Reader. You must have Acrobat to do it.
