Really Milt. You newbies never seem to RTFM. ;-)
Seriously though, I've never tried text, but I assume that it's the same deal. In
JavaScript, everything is an object, and text is just another object like a drop-down
list.
Check out www.devguru.com, who have a good reference on JavaScript.
My guess is that you probably have to create the text using JavaScript in order to
manipluate it using JavaScript.
Let me know (directly) if you figure it out.

Hmmm. Perhaps the difference is that I need to actually change the
text on the page instead of just the options in a list. Do you know
whether that makes a difference?

Agreed. In addition, this is only a slight divergence from the more
servlet-related question that started this thread.
