After following the Kirupa tutorial ([http://www.kirupa.com/developer/flashcs3/preloader\_as3\_pg1.htm](http://www.kirupa.com/developer/flashcs3/preloader_as3_pg1.htm)) on flash loading bars, I keep getting the following errors (see attachment) when I try to test it. Can someone help me debug this? I’m using Flash CS3.Ⓜ

are you importing the classes?

from the look of your error messages you should have these ;

```auto

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

```
