Problem with preloader

1

Hi ALL!

I’ve just started learning AS3 a week ago.
I’ve got a problem with my preloader. Here is the code.
The problem is when I load my swf nothing appears, I can hear the sound but no picture. If I load a jpeg it works but when I load the swf it doesn’t.
The swf is visible when I test the movie but when I “stimulate download” there is no visual just audio.

Thanks

///preloader///

var movieLoader:Loader;
function setProgress(value:Number) {
    mPreloader.mProgress.width = value*mPreloader.mBase.width;
}

function movieLoading(evt:ProgressEvent):void {
    var loaded:Number = evt.bytesLoaded / evt.bytesTotal;
    var percent:int = loaded * 100;
    mPreloader.tLoaderInfo.text  = percent;
    setProgress(loaded);
}

function movieLoad(url:String):void {
    mButtons.visible = false;
    mPreloader.visible = true;
    movieLoader = new Loader();
    movieLoader.load(new URLRequest(url));
    movieLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, movieLoading);
    movieLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, movieLoaded);
}

function movieLoaded(evt:Event):void {
    mPreloader.visible = false;
    mButtons.visible = true;
    mContainer.addChild(movieLoader);
}
movieLoad("tank.swf");
