Hi!
I'm afraid you might be running on Processing 4 where Python Mode is broken, it has the error messages silenced...
If you try on Processing 3.5.4 you might find it is a "Unbound local variable error" maybe (trying to increment a global variable without the proper global statement)?
Anyway, the best place for this discussion now, and for you to get help, is https://discourse.processing.org
