Mike, and everyone else, thanks for all the help!  I've been playing with
this since what I need is an update to the text box on the page.  I wish it
was as simple as sending someone to another page as soon as they clicked one
or the other.

Jonathan, thanks for letting me look at your code.  I tried doing something
inspired by yours, but kept getting errors on the page.  It expected objects
in various places, including the <body ...> line.  Other than that, your
example does exactly what I need to do, except for the other cool bells and
whistles you've got.  That stuff I don't need, just the plus and minus
buttons.

Again, thanks for all the help!  IC and this developers community rock!
