Traceback (most recent call last):

GLOBAL += 1
UnboundLocalError: local variable 'GLOBAL' referenced before assignment
And I don't know why :(
Anyone ?
Thanks!!
Assignment statements in functions implicitly make local names. If you
want to assign a new value to a global name in a function, you have to
use a global statement:
def update():
global GLOBAL
GLOBAL += 1
