But it doesn't, at least not in Opera. It does in every other browser I've used. But, Opera just doesn't pass it. Since I've tended to use radio buttons like that when I have a "doesn't matter" choice and then just done a LEN(mybutton) eval on the action page, I'm sure there's other pages of mine out there that will break in Opera.
