Help with this simple movie - undo check

Hey guys,

I need some help with this file. I need to make the radio buttons unchek. I tried using the Radio Buttons component, but I need to be able to select more than one.

Well, I figured out how to do that with very bad AS, but now I am having problems de-selecting them.

Any help would be greatly appreciated. Also, if there is a smarter way to do this, please feel free to chime in.

Thank you,
