Wheres the error in my script?

Your if statement on line 141 will end after the function KeyDown on line 144 will. Line 189 should be end) and line 190 should be end.

After going through and indenting your code correctly, there were a couple missing ends more misplacements like the one that caused your errors. I suggest you go back, indent the code, and make sure the ends line up correctly.

Edits:

Because I don't have all of the objects, such as the spell values in each player the script is calling for, I can't test it completely but it has no more errors dealing with organization.

I also highly suggest you read this wiki page.
