Ah! Thanks, tye...and parv, too...you both gave that excellent feedback. Now I understand...though I believe the author may have had a typo. But what you presented makes perfect sense...and reflects accurately exactly what happened. Learning things is great...especially when a mis-step leads to a much deeper appreciation of what's going on.

Thanks again to you both.

Sorry it took so long for me to get back to this...I only get an occasional chance, at work, to go out here and see how the Monestary is doing. I just discovered how to find all my previous nodes...that helps. This such an awesome monestary.
