Cloudbreak

I made a tic tac toe program (Turbo C) and I get this weird error message. Here's the code: http://planet.nana.co.il/danbar_6/TTT.C
Here's the error I get: "Linker Error: Undefined symbol _drawboard in module C:\Documents and Settings\Dan\Desktop\TTT.C"

I know there's no problem with the function drawboard() because I tested it without the rest of the program and it worked just fine.

Please help me solve this problem.

Thanks,
Dan.
