Expression must have class type?

Im working on Tile Mapping using SDL2, and so far stuff was going good, but for the life of me I can't figure out what I need to do to solve this problem. This is the error: Expression must have class type. Here is the class along with its' header. #include "Sprite.h" #include "includes.h" CSprite::CSprite(SDL_Renderer *passedrenderer, std::string Filepath, int x, int y, int w, int h) { renderer = passedrenderer; std::cout<<"Before\n"; image = IMG_LoadTexture(renderer, Filepath.c_str()); std::cout<<"after " << image<<std::endl; rect.x = x; rect.y = y; rect.w = w; rect.h = h; } CSprite::~CSprite() { SDL_DestroyTexture(image); } void CSprite::Draw() { SDL_RenderCopy(renderer, image, NULL, &rect); } void CSprite::SetX(int X) { rect.x = X; } void CSprite::SetY(int Y) { rect.y = Y; } void CSprite::SetPosition(int X, int Y) { rect.x = X; rect.y = Y; } int CSprite::GetX() { return rect.x; } int CSprite::GetY() { return rect.y; } void CSprite::LoadMap(char *name) { int x, y; FILE *Map; Map = fopen(name, "rb"); for (y = 0; y < MAP_MAX_Y;y++) { for (x = 0; x < MAP_MAX_X;x++) { fscanf(Map, "%d", &Map.tile[y][x]); } } fclose(Map); } void CSprite::DrawMap() { int x, y; for (y = 0; y < MAP_MAX_Y; y++) { for (x = 0; x < MAP_MAX_X; x++) { if (&Map.tile[y][x] != 0) { } } } } Header: #pragma once #include "includes.h" class CSprite { public: CSprite(SDL_Renderer *passedrenderer,std::string Filepath, int x, int y, int w, int h); ~CSprite(); void SetX(int X); void SetY(int Y); void SetPosition(int X, int Y); void Draw(); void LoadMap(char *name); int GetX(); int GetY(); void DrawMap(); #define MAP_MAX_Y 10; #define MAP_MAX_X 10; #define TILE_SIZE 32; private: SDL_Texture *image; SDL_Rect rect; SDL_Renderer *renderer; }; Thanks for any help, I'm going to attempt to solve this again tomorrow, but I've been a bit crushed on time recently.

A general rule I follow is, get it working first and then worry about a better way to do it. Not the best rule as it doesn't carry over to embedded systems very well at all, but for PC and the power they have, it is fine.
