Thing is, this is not my first time using several files when working with OOP and it is the first time i get this error.

EDIT: oh, wow, removed all files from the project, added them and everything works... Thanks for the help though

i personally had a bad experience wit code block , thats why i use TURBO C++ 3.07 or 4.5 or 5.02
