Here is my PHP script that creates the JSON data:
and here is the page that calls the list:
When I run the page I get the error but it does show the correct number of records (but shows no records) so something is working.
Can someone tell me what I am doing wrong and how to make it work?

Can someone tell me what I am doing wrong and how to make it work?
