How refer to selected Radio button value in forms?

Hi,
I use a dynamic form with xhtml that hides part of the form until the user select one of three radio buttons.

on submit, I validate different fields depending on the radio button selection. How do I refer to the radio button value that is selected? all the methods I tried show “undefined” as the value.
Thanks

@djbrinkauthorMar 20.2006 — I got the way to find the vlaue of a radio button on the following website:

it boils down to putting the radio button variable in a for loop first finding which one is checked, then extracting the value with another variable out of the array.

Now you know too.
