Get a nodelist containing all the radio buttons. You can do this with the document.getElementsByName() function
Iterate through the node list.
You can tell if a radio button is checked or not using its checked property
You can tell which radio button you're currently looking at by examining its value property
This should give you enough to get you started in the right direction. [ June 05, 2007: Message edited by: Merrill Higginson ]
