Despite my greatest efforts I have no idea why my code does not work. I believe it had to do with a single line of code that I accidentally deleted in recreating the code. My research has told me that the error message that I am receiving is either because there's a bracket missing or the code is too bad to work with. That's literally it: Most posts would tell someone to rewrite the whole damn thing and hope that fixes it. I checked all brackets and they were in order. Being provided with a reason as to why this error message would show up is what I am looking for.Any help you beautiful people would be willing to give is much appreciated.
