It comes down to what they call 'successful controls' http://www.w3.org/TR/html4/interact/forms.html#successful-controls I'm sure it makes sense to you that if you have multiple radio buttons of the same name only the checked one gets sent through on form submission. The same is true for checkboxes, though you can have more than on of them with the same name that is successful. I hope that helps somewhat... Paul McGarry
