True.  I'm relatively inexperienced with JavaScript and I just found jQuery
so I'm a novice as far as jQuery goes.

I would love to do that but each function has a different URL and I'm
not sure how I'd get the right URL with the right text using these methods.
I'll work on it though as it sure beats what I'm doing now. 

By the way I got the code I originally posted to work by removing it
from the loop and placing it in a series of IF statements.  It was a
test to see if the loop was somehow broken or the concept was broken.
Now that I know that I can get it to work I'll check out your suggestions.

I had already written (adapted, actually) the loadXMLDoc() functionality
before starting to use jQuery.  As soon as I can figure out how the $.get()
stuff works I'll be scrapping my old code.  Actually, I'll probably have to
use $.post() because I use session info to authenticate the user's request
with the ajax server process.   That might not be the best way but it was
the only way I could think of to enforce security like I do on the rest of
the site.

I have the API Reference bookmarked and looks

The AJAX related stuff is particularly opaque to me as they list a bunch
of functions but don't tell you which ones you need to implement a
working AJAX application.  I'm sure once I go through a few  of the
tutorials I'll be amazed.
