Accordion code not working

1

Hello all,

I am trying to put together a little accordion animation for a site. I am using code from this site:
http://www.freeactionscript.com/2009/10/simple-accordion-menu/

I only need 3 panels instead of 4 so I took the code and changed it to this:

package
{
/**
* Accordion Menu
*
* @author Philip Radvan
* @url http://www.freeactionscript.com
* @version 1.0
*
*/
import flash.events.Event;
import flash.events.MouseEvent;
import flash.display.MovieClip;

import gs.TweenLite;

public class Accordion extends MovieClip
{        
    var speed:Number = 1;

    public function Accordion()
    {
        card1.addEventListener(MouseEvent.CLICK, clickHandler, false, 0, true);        
        card2.addEventListener(MouseEvent.CLICK, clickHandler, false, 0, true);
        card3.addEventListener(MouseEvent.CLICK, clickHandler, false, 0, true);
    }

    protected function clickHandler(event:MouseEvent):void
    {
        if(event.target == card1)
        {
            TweenLite.to(card1, speed, { x:500, y:0 } );
            TweenLite.to(card2, speed, { x:0, y:0 } );
            TweenLite.to(card3, speed, { x:723.95, y:0 } );
        }
        else if(event.target == card2)
        {
            TweenLite.to(card1, speed, { x:352.95, y:0 } );
            TweenLite.to(card2, speed, { x:384.45, y:0 } );
            TweenLite.to(card3, speed, { x:23.95, y:0 } );
        }
        else if(event.target == card3)
        {
            TweenLite.to(card1, speed, { x:352.95, y:0 } );
            TweenLite.to(card2, speed, { x:384.45, y:0 } );
            TweenLite.to(card3, speed, { x:413.95, y:0 } );
        }
    }
}

}

You would think that SOMETHING would happen now. Even if its just a strange movement of some kind. But nothing does happen. Not even an error message of any sort. I started messing with that X and Y value but nadda thing. All of my movie clips are named correctly. card1, card2 and card3. Maybe it has something to do with the packages? I have never used components before like tweenlite. I took the files and just placed them in the folder with my flash movie. Was there another step I am missing? Any help would be appreciated. Thanks in advance!!!
