So I've been following this book that teaches you how to create your own games using the pygame module, I've copied out the code and recieved no errors but for some reason I cannot create a window.
In the previous exercise it works when I used [CODE]DISPLAYSURF = pygame.display.set_mode((400,300))[/CODE] but the only thing I can think of that has changed is instead of inputting the size, I've used a variable. I've looked at my code and cannot find anything wrong with it, any help would be MUCH appreciated. I realise a lot I posted is mostly irrelevant, but I didn't want to miss anything important out. Sorry about that.
Thank you in advance

You had the ifmain inside of hasWon and you were missing underscores, it needs to have double underscores on name and main

Also a good thread for questions is this one [url]http://facepunch.com/showthread.php?t=1167392[/url]
Thank you so much! Seriously, thank you! I appreciate you taking the time going through all that for me.
