I have an AJAX script that I call with jQuery which posts a request to a php file. The request is returned from the php file to the jQuery as XML. The xml is then returned to the template.

I have used this script outside of Znecart and it works fine. Now that I try to implement it in Zencart it does not work. The jQuery executes & the php file is found & executed but the request is not being posted to the php file.

Post is sent via jQuery :
'$.post("../common/tpl_load_content.php", {series: ser}, function(xml) {'

Post is read via php file:
'if(isset($_REQUEST["series"])) {'

Any help would be greatly appreciated.

As a side note, I think that I saw that there is a module for AJAX w/ Znecart for 1.3.8a. However, I am running 1.3.7 and management has denied the option to upgrade.
