SDL closes instantly

simpleasy (28)
Hi everyone,
I just started learning SDL for obvious reasons.

I used the following video as a tutorial:
http://www.youtube.com/watch?v=cE4KNkABQAY

However, when I run it, it instantly quits, and I have no idea why...
Maybe I made a typo somewhere that I keep overlooking, or maybe there's some other thing that is causing this.

Here is the code in my project (which should be the exact same as in the video)

#include "SDL.h"

int main(int argc, char * args[])
{
	bool running = true;
	
	//Init SDL
	 if (SDL_Init(SDL_INIT_EVERYTHING) == -1)
	 {
		running = false;
	 }

	 //set up screen
	SDL_Surface *screen;
	screen = SDL_SetVideoMode(800,600,32,SDL_HWSURFACE);

	if (screen == NULL){
		running = false;
	}

	SDL_Event occur;

	//main application loop
	while (running)
	{

		SDL_PollEvent(&occur);

		if (occur.type = SDL_QUIT) {
			running = false;
		}
		//Drawing occurs here
		SDL_FillRect(screen, NULL, 0);
		SDL_Flip(screen);
	}
	
	//Quit SDL
	SDL_Quit();

	return 0;
}



And this is what is printed under 'output' in ms visual c++ 2010 express:

Yep, a little typo :) if (occur.type = SDL_QUIT) should be ==
