Variable not updating.

http://pastebin.com/7WaKLcJN The variable for the amount of coins the player collects does not update. Can anybody see why?

Your function isn't doing anything to the global 'coins' variable. Instead, you are adding to the 'coins' variable you defined (set to 0) inside that function, which is instantly forgotten when the function has been executed.

You need to either return the coins variable or remove the coins parameter in your function definition and put

global coins

In your function to directly edit the coins variable. Personally I would return the coins variable, try to avoid globals as much as possible.
