MorganS:
The compiler is right. colorWipe() wasn’t declared. It was commented out with //
The // comment style only comments one line. It doesn’t follow the { and } pairs to comment out a whole block. So by putting in that single //, you’ve effectively removed a { from your program. But the matching } is still there. You will have a LOT of errors.
Expand the error window at the bottom of your Arduino screen. Scroll up to the top to find the first error. Fix that one first. That will solve a lot of the lower errors.
The compiler is very smart. If you define a function but never use it, it won’t get put into the final executable code. So you don’t need to comment-out unneeded functions. Although it is a good idea to prune them away eventually, so you don’t have a lot of unreachable code that you have to read past.
