I'm trying to recreate and run the dialog modal form example at http://jqueryui.com/demos/dialog/.  The source seems to be at http://jqueryui.com/demos/dialog/modal-form.html.  But when I copy the page and try to run it, the modal dialog doesn't appear.   The original source has a ton of js src files:

<script type="text/javascript" src="../../jquery-1.4.2.js"></script> 

<script type="text/javascript" src="../../external/jquery.bgiframe-2.1.1.js"></script> 

<script type="text/javascript" src="../../ui/jquery.ui.core.js"></script> 

<script type="text/javascript" src="../../ui/jquery.ui.widget.js"></script> 

<script type="text/javascript" src="../../ui/jquery.ui.mouse.js"></script> 

<script type="text/javascript" src="../../ui/jquery.ui.button.js"></script> 

<script type="text/javascript" src="../../ui/jquery.ui.draggable.js"></script> 

<script type="text/javascript" src="../../ui/jquery.ui.position.js"></script> 

<script type="text/javascript" src="../../ui/jquery.ui.resizable.js"></script> 

<script type="text/javascript" src="../../ui/jquery.ui.dialog.js"></script> 

<script type="text/javascript" src="../../ui/jquery.effects.core.js"></script> 

I'm only providing jquery.js and jquery-ui-1.7.2.js.  I downloaded the jquery-ui from 

http://jqueryui.com/download leaving everything checked.  Shouldn't this have everything 

from UI that the example needs?

Thanks for any help in getting this running.
