Gestureworks need help

1

hello im a AS2 migrant, AS3 is still pretty new to me.
i tried gesture works, i installed the file and then points the SWC,

i have a simple box named square_mc on the stage and i want to do a zoom and rotate gestures on it

heres the code:


 import id.core.Application;
    import id.core.TouchSprite;
    import gl.events.TouchEvent;
    import gl.events.GestureEvent;
    
    
        function startDrag_Press2(e:TouchEvent):void {
            e.target.startTouchDrag(-1);
        }
        function stopDrag_Release2(e:TouchEvent):void {
            e.target.stopTouchDrag(-1);
        }
        
        function gestureRotateHandler2(e:GestureEvent):void {
            e.target.rotation += e.value;
        }
        
        function gestureScaleHandler2(e:GestureEvent):void {
            e.target.scaleX += e.value;
            e.target.scaleY += e.value;
        }
                
                square_mc.addEventListener(TouchEvent.TOUCH_DOWN, startDrag_Press2);
                square_mc.addEventListener(TouchEvent.TOUCH_UP, stopDrag_Release2);
                square_mc.addEventListener(GestureEvent.GESTURE_ROTATE, gestureRotateHandler2);
                square_mc.addEventListener(GestureEvent.GESTURE_SCALE, gestureScaleHandler2);

and here are the errors:

Scene 1, Layer ‘Layer 1’, Frame 1, Line 15 1119: Access of possibly undefined property value through a reference with static type flash.events:GestureEvent.

so where did i screwed up?
