>Question 2:
>Is there a way of not executing the Click() event of an option depending on certain condition?

No, not as far as I know. However, you can subclass your option buttons,
and then add the subclassed buttons to the optiongroup at Init() time. As
far as your first question goes, I can't guess what the problem is, unless
3 isn't an option for that group, or the value is of the wrong type...
