var myVariable:String=MultiButton.groupName;
String
By specifying the same group name for multiple buttons, the button will act like a radio button group, when one is selected, the others will unselect. If the button has multiple states, the second state will always be initially selected and when toggled thru, the first state will never become active untill the button is no longer selected.
