John, We can't process you php code, so in order to help you, we need you to point us at a web page (privately if you wish) or create an example html from your page that hides your data.
If your want to debug this on your own, look in your browser's javascript debugger and note whether there are any errors reported. Another useful technique is to display a Table with your data, just to see that you are getting the data you expected.
