ActionScript 3.0 :: Adding Fast Forward Button To Animation

I would like to add a Fast forward button to my animation. I tried to modify existing AS2 code but I just cant get it to work. I'm getting errors about _root and it doesn't seem to like controller__mc. The AS2 version that works is:

forward_btn.onPress=function (){
_root.createEmptyMovieClip("controller_mc",1);
controller_mc.onEnterFrame=function(){
_root.gotoAndStop(_root._currentframe+3);
}}

And here is my sorry try at it in AS3:
forward_btn.addEventListener(MouseEvent.MOUSE_DOWN , playMovie);{
_root.createEmptyMovieClip("controller_mc",1);
} controller_mc.addEventListener(MouseEvent.MOUSE_DO WN, playMovie);
_root.gotoAndStop(_root._currentframe+3); {
stop();
}
