Try this file structure instead. I think you'll find it's much easier and a cleaner way to work, though i'm only guessing since i don't know your process. But at least in terms of what you're trying to do here, this should work out better for you. How To AI Files (1).ai - Google Drive
As to your question about debugging, check out Adobe's "ExtendScript ToolKit". That's the environment for debugging and testing scripts. Search the forums if you have trouble, there are tons of posts about getting it and using it.
Also to be clear, I was saying that the script should duplicate the live paint object and then expand it. That way the script can count the cells of the expanded live paint object and then delete it when it's done so you still have a fresh, unharmed live paint object that you can make adjustments to. Give this a try:
/*
Script Name: getCellColors
Author: William Dowling
Date: 4/6/18
Required:
--Illustrator CS6+ (any platform)
-An Illustrator file with one or more layers which contain
only one live paint object. Each live paint object should live
on its own layer.
-The live paint objects should be colored in using RGB, CMYK,
or Spot colors.
-The live paint objects should be constructed out of plain rectangles.
Beware:
-There is very little to no error handling, and even less testing.
Please make sure to save your work before running the script. You
are solely responsible for any artwork/time lost as a result of the
failure of this script or Illustrator crashing or whatever. Just
protect yourself, please.
