You're very good at understanding it and wish I had your explanation when I was going through it. You absolutely cleared the "cobweb' for me and, surely, when I return to that section, I shall understand it from that perspective! Well, Mc..., you will definitely benefit from SL's explanation and will avoid the problem I had!!!! That will make it a smooth sailing for you, ha, ha, ha!!!
Again, SL, a million thanks!!!!
