AS3: Need active states for movieClip buttons

1

Below is the code I have for my buttons. I have 3 different swfs loading in once each corresponding button is selected (CLICK). I also have rollover and rollout or idle states. Now the dilemma: Once a button (mc) is selected (CLICK) I need it to remain in its rollover state. Once another button is selected I need the previously highlighted button to switch to idle state and the new button to be highlighted… Sounds like the most basic, simple, AS3 101 question, but alas I am hitting a wall. Based on my provided code what is the best option for this, an array with an active state on the timeline, a toggle with Boolean ect, ect…?

Please help, any and all assistance is as always greatly appreciated… :thumb2:

var Hotspots:Loader = new Loader();
addChild(Hotspots);

moreInfo_btn.addEventListener(MouseEvent.MOUSE_OUT,changedColor);
function getInfo(MouseEvent):void {
        Mouse.show();
        rotate_mc.alpha = 0;
        Hotspots.load(new URLRequest("HiltiCallouts.swf"));
        Hotspots.y = 20;
}
