getKeyState missing ) before ; in VC++ 2008

I'm currently in the process of creating my first 3D application using the OpenGL library and it's been going great until now where I seem to have encountered a little hiccup in my main source code.

void Keyboard_Input()
{
 if(GetKeyState(VK_UP) & 0x80)
  Move_Camera(CAM_SPEED);

 if(GetKeyState(VK_DOWN) & 0x80)
  Move_Camera(-CAM_SPEED);

 if(GetKeyState(VK_LEFT) & 0x80)
  Rotate_Camera(-CAM_SPEED);

 if(GetKeyState(VK_RIGHT) & 0x80)
  Rotate_Camera(CAM_SPEED);
}


When compiled I get the following error on each line where each condition would be met (e.g. Move_Camera()):

error C2143: syntax error : missing ')' before ';'

Everything surrounding this code looks okay and <windows.h> is include but I'm not sure where even these are turning up errors. Any help would be appreciated.

It will have told you the line number too. Check the line.

Okay, this is beginning to really irritate me. This is the first chunk of the code where the problem lies (I assume):

O.O

...hence, VC++ 2008 is not good for locating errors. Ugh! Thanks Gumbercules.
