Wow! 12 piece, you are a prince. These many different uses of the word, "plane" were definitely a problem for me, mainly because I often could not tell which plane was being referenced. I very much appreciate your taking the time to respond so thoroughly. I'm going to print your post to keep as my "cheat sheet." Oops, a teacher should never use that term
Thanks again.

P.S.- If it's not too personal, I'm curious about the origin of your screen name.
