UDM breaks form input field--help?!

[justina.brown]

We have a custom .net search tool on our site that was working great until I implemented the UDM horizontal menu. Oddly, in IE, the only thing "broken" is the input field. If you select search "events" and leave the input blank (because you have to) and click "go" it still functions. It just won't let you type in the text field. Although, it won't work at all in FF.

If I eliminate any one part of the menu (the ul, or any ONE of the js files), then the text field works again.

For instance, commenting out any one of these makes it work:
<!-- <script type="text/javascript" src="udm-resources/style-getaway.js"></script>-->
<script type="text/javascript" src="udm-resources/udm-control.js"></script>
<script type="text/javascript" src="udm-resources/udm-style.js"></script>

Here is my page with the bunk search field (no parts of UDM deactivated):

Here it is with the UDM ul hidden:

Any ideas?? I'd really appreciate some help as we're about to populate our large website with this template.
