[SOLVED] Javascript not working in widget sidebar

Hi -

I'm trying to set up a tabbed menu on the sidebar. Tried a few others, including Tabbed Widgets and Section Widget, and came across the same stone wall: javascript doesn't appear to work in the sidebars.

I've deactivated all my other plugins in case one of them may be causing the problem, but no....

Currently, I'm playing with NetTut's jQuery Tabbed Interface example.

My test page shows the tabbed menu working in the main content section of the post. However, the same code in the text widget on the same page doesn't work (although the CSS works fine!).

I've got this test page going on 2 separate websites, both using Wordpress 2.9.2 and Atahualpa 3.4.6.

Apart from the plugins that I've tried, this is my second attempt at doing a tabbed menu the hard way. I've run out of ideas of why they don't work. Please help!

Thank you for your help in advance!
