Pointers and tips on Javascript errors - Noahj

WPMU!! What up?

I pretty much do everything self taught online. Self taught meaning studying or reading of course from pro's, etc.

However I need to fix a couple Javascript errors in order for a plugin author to help me with a plugin bug, as the javascript errors may be the sole problem.

I just would like some tips on where to learn, analyze and resolve Javascript errors. I'm not down with the get down yet on Javascript yet.

Blast me a tip on this, please.

Word up, greatly appreciated!

(Screenshot attached is a sample of what I need to fix.)

Kind regards TeamWPMU,
