XML HTTP auto download of orders

[ZoXo]

I am trying to use the XML HTTP import for orders. I am using FileMaker Pro and have successfully imported the XML file, but I am having trouble with the HTTP URL. When I enter the URL into the browser it downloads the XML file, but when I ask FileMaker to script the XML import, it errors out on the HTTP request and will not import anything. The URL has successfully been used for StoneEdge but is for some reason not valid in a FileMaker HTTP request. Any help would be appreciated.
