Flash preloader help!


Was wondering if someone could help me in getting some kind of preloader to display when I call an image from an xml file into an empty movie clip, please?

I have this piece of code in my actionscript on the first frame of my movie,(amongst other code), which i think has something to do with it.

bitlistener.onLoadProgress = function(target:MovieClip, bytesLoaded:Number, bytesTotal:Number):Void  {
        amountLoaded = Math.floor((bytesLoaded/bytesTotal)*100);

on the second frame i call the image/xml:


how would i add a something that displays the loading progress of the image being loaded from the xml?

many many thanks.
