Help loading an external SWF

[Ninjamark]

Hey guys, So I've pretty much finished making a site, I just need a gallery. To make it easily edited I decided to use the
Photo Gallery Maker program, found here: http://www.photogallerymaker.com/

But I keep getting an error loading this and I have no idea how to fix it, the error is:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at GalleryLoader()[E:\Projects\GalleryMaker\FlexSource\GalleryLoader\ src\GalleryLoader.as:23]

The code I'm using is this:

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("WG3.swf");
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();

Your error looks like it is coming from the actionscript file for the GalleryLoader. The Error #1009 comes from trying to talk to something that is not there... Check this article: http://curtismorley.com/2007/08/15/f...ect-reference/

Does the gallery play fine in its own swf? and now you are having trouble incorporating it into your file?
