}errors i am gettign are :
parse errors on lines 85,102,111,121,307
im also getting told that "IOS C++ forbids decleration of..." on lines 109, 110, 118, 120
there are also other errors withing that part of the code, what is weird to me however, is that it works perfectly fine in the other place that the almost identical code is placed (status 2)
