jQuery Forum

I'm confused why this (seemingly out-of-the-box) jquery widget isn't working.

This is in the HEAD of the doc (paraphrased here!):

[code]
...script type="text/javascript" charset="utf-8" src="jquery.js"...
 
...script type="text/javascript" charset="utf-8" src="jquery.core.js"...

...script type="text/javascript" charset="utf-8" src="jquery.ui.tabs.js"...
[/code]

But I'm getting a javascript error: "d.widget is not a function"

I'm calling the jquery function from an external .js doc that I call after the above calls:

[code]
$(document).ready(function() {
    $("#tabs").tabs();
  });
[/code]


I don't think I've made any dumb syntax errors here...any advice?
