Mutually Exclusive check boxes not radio buttons

I have a situation that calls for Mutually Exclusive check boxes not radio buttons. The problem is that I have check boxes that tell a text field to show different text depending what check box is selected. However I need only one box to be checked at a time. I know this sounds like a radio button but because of what I'm doing I need the check box because I need to place text in the on/off value in the binding tab to make my script work. I will attach an example with screen shot. My script in the change event is as follows

if

= "visible";

Procedure.rawValue

= "Child Procedure";

So Ineed my child, teen,, and Adult field to tell the other 2 fields to be not checked when they are checked like a radio button.
