I honestly have no clue what the heck is going on?

Well I have been working on this same problem for over an hour a day, and it wont go away, I feel like its something so obvious I want to punch myself, but I cannot figure out what.

wait(5)

I've checked the output, I've tried remote error monitoring script, and nothing shows me anything.
