Sometimes Broken Script or file renaming

Hey Chad!

A while back this script was written for me by sam, and for some reason it just......breaks. The conditions never change, but it just doesn't work. IT's frustrating too because it's the script I need to work the most. Is there something that is identifiable in your opinion that would cause it to not find elements that cause it to break?
