then the program should take the information and depending on the performance level.. (the number after their name) calculate their new salary and increase rate. However, I am unsure if I have the formatting right for the output and input and I also have the link1169 error. Any help would be awesome.. Thanks

what is a link1169 error?

Can you post the error message?
Nvincent4708 (8)
Visual Studio 2008\Projects\project1\Debug\project1.exe : fatal error LNK1169: one or more multiply defined symbols found

that is the error i'm getting.. not quite sure what it means though.

Is that file your showing the only one? Or is there more files?

Because you may have main defined twice or something

you're right, it was defined twice. All is well now it works. Thanks very much. I can't believe I made such a mistake.
