LG, I was responding to the original post as quoted below:

I'm trying to create a little function which will check to
see if the user has selected an option in an option array.
So I think I am safe because as far as I know, Option
Buttons always have the .Value property.

All I was demonstrating is that the method being used to
address the individual elements of the control array was
not safe. It was a given fact that the control array was
going to be of Option buttons

Nice to know you took a look at the samples though

Cheers
