#include problems

What are you trying to include? do you have any code, that might help a bit if i can see your code.

You''re probably defining a variable or function multiple times. Since this question gets asked every other day, you might like to do a forum search to find out the workaround.

Better than a forum search, how bout a tut from Kylotan?
