    Okay I fixed the issue by not referencing variables outside the scope of the function. So I passed in lines as an argument to get_color and current_point as an argument to get_next_state. Still, I wonder why this is necessary. I thought that I should be able to access module variables from within a module function.

      I found out if I relocate these two lines. (see attached) It seems to pass the error.
