The function is treating the variables SPRITE_SPLASH & IMAGE SPLASH as local to the function and therefore have values of 0.
You need to specifically declare the variables with the 'global' command i.e.
global SPRITE_SPLASH = 1
Alternatively pass the values to the function, or use a subroutine instead of a function.
