Thanks Eliyahu. I finally got the thing working correctly.

Now here's the next problem - when I originally load the page, I don't have
anything filled in so I know the startup state. But there are conditions
where I will pre-load the page values which means I need to be able to set
the screen accordingly.

In other words, I need to be either able to set the visibility from both the
client side and the server side, or I need to be able to on page load call
some javascript to be able to activate the appropriate items.

(I'm also going to post a separate item in here for this same problem.)

Any suggestions?

Thanks - Jeffrey.
