An urgent question on jquery UI


I have an urgent question on jquery UI. Maybe you could help me with
it. I am planning to use jquery UI theme, found at:
http://ui.jquery.com/
I select a theme at
http://ui.jquery.com/themeroller
Download the theme, then in the downloaded jquery-ui-themeroller
folder, there is a demo.html file, and a ui.theme.css style sheet. I
am trying to use the UI components provided by jquery UI, and
following the coding frames in the demo file. However, as you can test
yourself, all the UI widgets don't work!
I found that the two js scripts links are broken in the demo.html
files, so I downloaded jquery.js and jquery-ui.js from the web, and
put them in the directory, but still I can't make the demo file work.
Could you help me look into this?
THanks!
