Oops - I thank you, very much - but the resulting protocol is way over my head at this time. (I tried copying and pasting the table as requested but haven't figured out how to maintain/format it, etc.) It really was not apparent to me the involvement necessary having only read the content of this post, to which I responded directly. I feel terrible for not following this through, but the commitment required was not clear to me and I must humbly petition for a fork in this chain. Yikes :(
