Wait a minute! Are you saying that you have 4 buttons of which
the 'ON' state value of each of those buttons is "on"?
If that is the case, you are completely misunderstanding the
concept of radio buttons. Imagine you have to submit such a
form to a server, then the server would always receive
"nameRadiobutton=on" no matter which radio button is selected.
That's not an invalid form, but it doesn't make sense either.
If that is the case, you should change your form.
