Great info Mike and thank you for clarifying this for everyone. This one, for me at least, was a difficult one to decipher. I had several ideas (which all were wrong...lol) but thanks for chiming in with your bank of knowledge. Still loving Error-Ref you produced. Don't believe there's a single topic on your site that has not been covered, and in great detail. I believe I can say, speaking for others as well, we are very appreciative of your awesome website, help and knowledge. Thanks!
