Preloader in AS3

This wee preloader script from I<3 actionscript works a treat:

import flash.net.URLRequest;
import flash.display.Loader;
import flash.events.Event;
import flash.events.ProgressEvent;

function startLoad()
{
  var mLoader:Loader = new Loader();
  var mRequest:URLRequest = new URLRequest(“MouseActions.swfâ€);
  mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);
  mLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);
  mLoader.load(mRequest);
}

function onCompleteHandler(loadEvent:Event)
{
        addChild(loadEvent.currentTarget.content);
}
function onProgressHandler(mProgress:ProgressEvent)
{
  var percent:Number = mProgress.bytesLoaded/mProgress.bytesTotal;
  trace(percent);
}
startLoad();
