SDL Problem

I just made a bitmap image in paint, saved it as a 24bit bmp. what im trying to do is get this bitmap loaded and onto the screen. here is my code thus far, am i doing something wrong??

	SDL_Surface *screen;
	SDL_Surface *image;

	image = SDL_LoadBMP("d:\1.bmp");

	if (image > 0)
	{
		SDL_Rect sdest;
		sdest.x = 10;
		sdest.y = 10;
		SDL_BlitSurface(image, NULL, screen, &sdest);
	}
