I am trying to make a dynamic slide show with thumbnails. The tutorial on [Kirupa.com](http://Kirupa.com) is great! But I want to update it to AS3 and move the code out of the timeline into a class file (called XMLSlideShow). So far so good. Targeting Flash 9.But I am getting error #1056: Cannot create property preloader on XMLSlideShow.at flash.display::Sprite/constructChildren() at flash.display::Sprite() at flash.display::MovieClip() at XMLSlideShow()In debug mode, it highlights line 12 "public function XMLSlideShow(){ " Here is the rest of the code. Can anyone help? I am pretty new at this but trying to learn.
