There's some discrepancy between the description of the problem and the code.

I know that the description of the problem is misleading but looking at the code in the original post, and the comment about the suggested solutions working, what the OP is trying to do is trap the situation where there are no radio buttons selected.

Your code can easily be extended to do this but as it stands it doesn't actually achieve what he set out to do!
