This cant be the best way to make Button Rollovers

1

I currently have a flash file that has a whole bunch of buttons that are MC’s with rollover and out states that open up a PDF when clicked.

For each number (12-33) I have the MC with a new instance name and I am calling them with the following code:


stop();
over12.addEventListener(MouseEvent.CLICK, over12Click);
over12.addEventListener(MouseEvent.MOUSE_OVER, over12Over);
over12.addEventListener(MouseEvent.MOUSE_OUT, over12Out);
function over12Click(event:MouseEvent):void {
    navigateToURL(new URLRequest("catalog/12.pdf"));
}
function over12Over(event:MouseEvent) :void
{
    event.currentTarget.gotoAndPlay("over");    
} 
function over12Out(event:MouseEvent) :void
{
    event.currentTarget.gotoAndPlay("out");    
}

So for each button I have this huge mess of code. There has to be a cleaner and more efficient way of doing this. Can you guys suggest anything?
