Jeez, I'm grateful for your fast reply, but am confused. Perhaps I should
restate the issue briefly.
I retrieve an ordered list from the database that I can easily display on
screen. No problems displaying the list in correct order. With a little
script.aculo.us magic, I can move the <li> elements around, and thus change
(on-screen only) their order.
How do I get that new order back into the application from the web page?
Does a hidden field really help? I don't see how...
Cheers!
