Point taken, and my apologies to you regarding the code. Given that your code was correct when sent, each of three times, the burden lies on the site editors to make sure that the listings are correct. Which, come to think of it, is where the burden lies from the get-go... *shrug*
I'm glad to hear I did understand correctly. What are your thoughts regarding my contention that O/R technology is, as yet, not mature enough for more than basic use? Am I correct, and to what degree? I suspect that you, as the domain expert, know fifty-dozen ways to get around the limitations (and I should, of course, read your book...), but are they "easy enough" yet? What are the flaws in the current implementations, and what would you change if you could?
Thanks for your input.
