Troubleshooting: Extending the jQuery Sortable With Ajax & MYSQL
===

I'm trying to implement an ajax tutorial I found at http://linssen.me/entry/extending-the-jquery-sortable-with-ajax-mysql/

The tutorial allows for cligf-and-drag sortable bullet lists...where each item's position is updated in the database. 

There's an info box that shows what changes have supposedly been made, but there are no changes made to the database. 

I've gone over the tutorial a hundred times and I have no idea what could be the problem.

I could use a second pair of eyes.
