I might be able to help, I took a class on coding, and I've messed with it off and on over the years, I'm no expert though

The trouble I usually have though, especially when going through someone else's work, is knowing what all the variables are for, and what obscure uncommented blocks of code are accomplishing.
Knowing how to get a desired effect on something that's intertwined with dozens of other sections can be a pain in the ass too... You change one little thing and suddenly a handful of things go haywire.
I'll help if I can, maybe I can look over it and decide if I'm crazy to even try.
