I’ve been working on this for sometime, and I am starting to clench my teeth…Could someone take a look at this and tell me why if I substitute \* with [1] I can get the next image to pop in to the loader, but otherwise I get error 2007: Parameter url must be non-null…

```auto
var imageContainer:Loader=new Loader();

addChild(imageContainer);

var loader:URLLoader=new URLLoader();
loader.addEventListener(Event.COMPLETE, xmlLoaded);

var request:URLRequest=new URLRequest("images.xml");
loader.load(request);

function xmlLoaded(event:Event):void{
    var xml:XML=new XML(loader.data);
    trace(xml.pic[0]);
    var picRequest:URLRequest=new URLRequest(xml.pic[0]);
    var picLength:Number=xml.pic.length();
    var picLoader:Loader=new Loader();
    picLoader.x=picLoader.y=50;
    this.addChild(picLoader);
    picLoader.load(picRequest);
    var myTimer:Timer = new Timer(5000,2);
    myTimer.addEventListener(TimerEvent.TIMER, nextImage);
    myTimer.start();
    function nextImage():void{
        picLoader.unload();
        for(var i:int=0; i<=picLength; i++){    
            var nextPicRequest:URLRequest=new URLRequest(xml.pic*);
            picLoader.load(nextPicRequest);
        }
    }
}

```

thanks.
