Indeed that did solve the problem. Thank you!
If I may borrow just a few more seconds of your time, I'd like to also try to deal with the issue that always comes up whenever someone in a forum kindly shows me correct code.
Yes, it fixed the problem, but I'm left wondering what was the error in technique that led to the formerly-broken page? If I can learn that, I won't do it again and I won't have to be on this forum looking kinda like I don't know what I'm doing!
