Flash + PHP + SQL integration tutorial

I’m currently trying to follow the tutorial on integrating Flash with SQL via PHP.

tutorial: http://www.kirupa.com/developer/actionscript/flashphpxml_integration.htm

I have a working php/sql server and I’ve downloaded the source files of the tutorial.

When I run the sites.swf, the list is empty. But I know sites.php is accessing my database and reading the rows from the database properly.

Is there something that needs to be modified to get this tutorial to work? I’m using Flash CS3 Professional.
