Error 1009, instantiating a class that extends a Sprite

1

Hi! I’m new… and yeah, any help would be greatly appreciated.

I’ve tried calling constructor class from my main.fla, and it just doesn’t work. The error when I try to instantiate the constructor is that it needs an argument… and since the class extends a Sprite… and I’m kinda at a loss. Help?

	public function portGal():void {

			this._images = new Array();

			this._app.sWidth = stage.stageWidth;
			this._app.sHeight = stage.stageHeight;
			this._currentImageID = 2;

			var xmlURL:String;
			var xmlLoader:URLLoader = new URLLoader();

			xmlURL = "folioList.xml";
			xmlLoader.addEventListener(Event.COMPLETE, parseXML);
			xmlLoader.load(new URLRequest(xmlURL));
		}
