I am trying to finish this program that is due tonight. I have been working on it through out the week and thought I could figure out my errors with fresh eyes. I have got the number of errors down, but for some reason I keep getting errors like string is undeclared in line 12 or playerNameAr undeclared. There seems to be a lot of undeclared identifier and I can't figure out why.
