I looked that up and see your point. Unless I missed something though, it involves renaming everything to work in the namespace. That's more than I want to do right now and probably above my skill level. Unless there's a simple way to do this by say, adding something at the start (and maybe also end) of every file, while leaving the basic func defs & calls alone, I'll defer this to later when I can bring on a professional programmer to upgrade the code. As of now, there's just this one group of scripts and I haven't seen any conflicts.
But thanks for the heads up on it; I'll definitely put it on my list for future upgrades.
