Help with Audio Visualizer Script

Hello! I’ve been following the tutorial over at CG Cookie, and I’ve hit a snag. I’m completely new to scripting in Blender, and I really have no idea what I’m doing. I copied Patrick’s script at the end, and when I try to run the script, I get and error, and I’ve got absolutely no idea what it means. Below is a link to my Python code and my .blend, if that will help. I would really appreciate any help in this area. Thanks! :slight_smile:

I looked through the thread, but I’m really lost. I’ve got no idea how/where to enable his add-on.

Double post, sorry.
