Uncheck radio button

Hey guys.

This might be really stupid but I’m a little confused.

I have a radioButtonList element and would like to have the radio buttons uncheck when they are clicked again.

The issue at hand is that I have a radio button list in which I can only select one element (hence the radio buttons) but not selecting anything should be a viable option as well. As it stands, once I select an option I can’t revert back to a totaly unchecked list.

How would I go about achieving this? I can’t seem to be able to get any checked/unchecked status from the radios with javascript. Maybe there’s a layer I’m missing? Should I pop my javascript into htmlOptions?

Thanks in advance
