Loading external content on top of main content

Hi all,

I’m loading one SWF into another but the internal one is coming over the main content and that can’t happen.

here is the part of my code where the external content is being loaded anyone has any ideas on what I can do to fix this?

thanks a lot here is my code:

var loadAnimBox:Loader = new Loader();
var vid_mc:MovieClip;

function startLoading():void {
    loadAnimBox.contentLoaderInfo.addEventListener(Event.COMPLETE, onBoxLoaded);
	loadAnimBox.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onBoxProgress);
    // load the box animation SWF
  	loadAnimBox.load(new URLRequest((meuCaminho.parameters.cont) + ".swf"));
}

function onBoxProgress(e:ProgressEvent):void{
	//trace(e.bytesLoaded,e.bytesTotal);
}

function onBoxLoaded(e:Event):void {
    loadAnimBox.contentLoaderInfo.removeEventListener(Event.COMPLETE, onBoxLoaded);
	loadAnimBox.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, onBoxProgress);
    vid_mc = loadAnimBox.content as MovieClip;
    // We listen for that event:
    vid_mc.addEventListener("firstAnimationComplete", onFirstComplete, false, 0, true);    
    addChild(vid_mc);
    vid_mc.addEventListener(Event.ENTER_FRAME, playProgress);
