That's perfect, Rick, it's exactly the way I would have coded it.
Hang in there on this client-side stuff! It will all continue to become more
clear as you work with it.
I have some sympathy for what you're going through with it. As more of a
front-end guy, it happens to me every time I tackle back-end stuff like
databases. Help me! Databases! Why can't it be something simple like
closures and asynchronous Ajax calls? ;-)
