Within the "Style" group I have two radio buttons, "A" and "B". How do I alter the above script to just set radio button "A" to read only?
Not possible. The "read-only" property applies to the entire group as a whole.
Thank you for the info.
I don't know if would help in your situation, but you can hide one or more radio buttons in a group. This would make it unselectable, leaving any unhidden ones selectable.
