lol. There's another wrinkle for my brain. I have always used it, but I can't think of a time when I used the same variable at a functional and global level. Idk.. I'm anal about my variables though. Of course good programming aside, I was under the assumption that I couldn't use the same variables with the Option Explicit so doing the right thing, but maybe not 100% for the right reason.

I usually give a prefix to any variable corresponding with it's scope. gb_X for a modular level variable vs an 'X' in a single sub or function.
