    include files not working?

    i am having issues with adding functions to a program that has a couple of my own header files and uses a couple of source files,

    it works ok and compiles, but now when i am adding new functions i keep getting hassle from the compiler, its basically telling me functions are not declared in scope or elements that i am passing to function are not declared,

    in the example below i cant understand why the following is not working >>

    here is one of the header files, declared in main() as #include "graphic.h"

    Code:
    #ifndef GRAPHIC_H_INCLUDED
    #define GRAPHIC_H_INCLUDED
    
    SDL_Surface *screen;
    SDL_Surface *temp;
    SDL_Surface *PegArea;
    SDL_Surface *Buttonarea;
    SDL_Surface *Gameboard;
    
    void DrawGameEvent(GamePieces solpeg[MAXDWN][MAXACR], bool peg_chosen);  //this is existing stuff that works fine 
    // > function is implemented in project source file GraphicSource.cpp
    
    void RefreshBoard(GamePieces solpeg[MAXDWN][MAXACR], MenuButton* pMenu); //this is existing stuff that works fine
    // > function is implemented in project source file GraphicSource.cpp
    
    void DrawBoard(); //this is my example that is not working  created just for this test, function is called in main() 
    //and implemented in project source file GraphicSource.cpp 
    
    
    #endif // GRAPHICS_H_INCLUDED
    
    #endif // GRAPHIC_H_INCLUDED
    the call in main() is like this >

    Code:
          InitBoard(solpeg);
          Drawboard();                           //the offending function
          Menu.InitButtons();

    the function itself in the source file i just wrote as

    Code:
    void DrawBoard()
    {
    
    }
    is there anything wrong with this? do i need to put some kind of arguments into the linker or something or am i missing something simple?

    functions are not declared in scope or elements that i am passing to function are not declared,
    Which one ? could you be more specific ? also based on the code you provided I would assume that its because your DrawBoard function has an uppercase B whereas in main your calling it with a lowercase b.
    Spidey out!
