Thread: namespace problem? maybe...

I have a problem with my header Surface.h. Which is basically just a set off inline class for SDL_Surface and limited animation. The animation is where my problem is.
I have Graphics.h which is a simple wrapper for some SDL procedures (surface loading, blitting, and freeing).

the line with the error is commented, and in red.
Graphics.h - No problems with this file.

Code:

#pragma once
#include <SDL.h>
#include <SDL_TTF.h>

//
#include "ErrorValues.h"
#include "Surface.h"

namespace varia
{
    class Graphics
    {
    public:
        Graphics();
        ~Graphics();

        //Initialize SDL and the display surface
        int Init(unsigned int windowWidth = 800, unsigned int windowHeight = 600, bool fullscreen = false,
                 const char* windowTitle = NULL, unsigned int bgR = 0, unsigned int bgG = 0, unsigned int bgB = 0);

        int createSurfaceFromFile(Surface& dst, int tran_r = -1, int tran_g = -1, int tran_b = -1);
        
        void closeSurface(Surface& src);

        int drawSurface(Surface& src, SDL_Rect* clip = NULL, unsigned int x_pos = 0, unsigned int y_pos = 0);

        int beginScene();
        int renderScene();

    private:
        SDL_Surface* m_screen;

        unsigned int m_bgR;
        unsigned int m_bgG;
        unsigned int m_bgB;
    };
}

Surface.h - Error in the Animation class

Code:

#pragma once
//Still surface
namespace varia
{
    class Surface
    {
    public:
        Surface(const char* FILE):m_file(FILE),m_surface(NULL)
        {};
        ~Surface() 
        { 
            if ( m_surface != NULL )
            {
                SDL_FreeSurface(m_surface); 
                m_surface = NULL;
            }
        };

        SDL_Surface*& getSurface()
        { 
            return m_surface; 
        }

        const char* getFile() 
        { 
            return m_file.c_str(); 
        }

    protected:
        std::string m_file;

        SDL_Surface* m_surface;
    };

    class Animation : public Surface
    {
    public:
        Animation();
        ~Animation();

        //If clip does not exist it will create one ( or overwrite ) to the keyID provided
        void SetClip(int keyID, int x, int y, int w, int h);

        void Animate();

        int Show(varia::Graphics* graphics);//Error: 'Graphics' undeclared identifier

    private:
        //The Animation Timer
        Timer* m_timer;

        //The region vector
        std::map<int, SDL_Rect> clips;

        //animation vars
        int m_frame;
        int m_endFrame;

        float m_framesPerSecond;
    };
}

This makes no sense. I have Surface.h included before Graphics.h and even if i put #include "Graphics.h" in the Surface.h it won't work. I am lost for a solution.
It will be greatly appreciated if anyone has a insight to my problem.
