Thanks for your comments on my query, especially to Arden, who is absolutely amazing. I would never have the patience to go into so much detail! Sorry for not answering sooner, but I was busy writing that second query. (note my new name!)
No. I'm not posting the second query here. I have a good feeling about it and I don't want anyone picking over it again, but I used a lot of your helpful advice. Thank you very much.
