Flash MX Action Script 2.0 Platformer Game Problem

I’m in the process of building a platformer with Flash MX using Action Script 2.0, I’m following this tutorial: http://www.kirupa.com/developer/mx2004/platform_game.htm However I’m not following the tutorial, I downloaded the .fla file and followed that. The .fla file available for download functions, but my recreation does not.

I have used all the elements from the tutorial platformer, the scoring counter, the health counter, the pickups, the enemies etc. But it does not work properly.

Here is my attempt for download, can someone please explain where i’ve gone wrong, and if it’s not too much trouble, fix it.
