Hi Mark,
Thanks for the compliments. Sherry and I did put in a lot of time, and had a lot of fun doing it. I also learned a lot from the experience. I think working with others adds motivation. Working with Sherry made the whole thing really interesting. I agree with you, it would be great to have more of this type of collaboration on the forum. I am thrilled to have had the opportunity to work with someone with so much skill. I welcome any chance to do it again.
Fred
