Yes, that is totally what I'm looking for--you were right! Thank you! You solved it!

That page doesn't explain well at all what entity names are, so it lost me. I can see what they're trying to explain now that you explained it to me in clearer language. And that's the language I'm trying to use in my beginner's guide, which is what the 3schools site could use there, and most especially on its introductory pages--I was looking at those and they start out really badly.
