Sorry, you're right. The OP's question threw me off by saying that he
wanted to ensure that at least one of the choices was picked. I didn't
realize he was talking about radio buttons where you either get /one/
thing or nothing.

If he's got checkboxes (which is what I was thinking, even though he
clearly said radio buttons) or multiple unrelated radio buttons,
validwhen may be necessary. But probably not in this case.
