Loading interactive swf - How do you do parent in as3 / probably a simple problem!

programming flash
1

Hi I have this code from as2

                                             this.onEnterFrame = function() {

_parent.timelinebeethoven.loadMovie(“content/interactive/beethoven.swf”);
}

That loaded up an external swf.

Now I’m building an interface in as3 and I"m using this code to load up the movie with a button.

                                              var myLoader:Loader = new Loader();

box2.addChild(myLoader);

beethoventime_mc.addEventListener(MouseEvent.CLICK , mouseDownHandler22);
function mouseDownHandler22(event:MouseEvent):void {
gotoAndStop(“beethoventime”);
var myURL:loadmovie = new URLRequest(“beethoven.swf”);
myLoader.load(myURL);
}

It loads up great, and I thought I was all set - but the interactive elements are not working correctly.
I think the problem is this “timelinebeethoven” and parent are really in the as2 code is not at all in my as3 code and they are really important.

Does anyone know how to add in these two pieces into my as3 code?
I feel really really really stupid asking this - it’s probably so obvious.

THank you thank you thank you!!!
