Google Closure Compiler Extern Help

[mrbinky3000]

Anyone out there knowledgeable on Google's closure compiler? I got started but need someone with expertise on the subject to finish it up. I have 9 warnings left that I'd like to get rid of but don't have the time to figure out right now. Help me out! Get some credit!

Perhaps it would be helpful to post the warnings here?
