In regards to the problem with the Add button not working, I've narrowed it down to being a problem with the IUI code (
http://code.google.com/p/iui/). As to the exact problem, I'm not sure. Could be how the HTML code is formatted. Could be a CSS issue. Could be a javascript issue. Not entirely sure. But I do have a static HTML page that I'm working off of so I can strip it down till it doesn't fail anymore. :)
