Thank you for that information. I am now getting an error on the confirmation of:
ERROR: Invalid value in element ReturnShipmentIndicator.
I did not change the Return Type and it was working before I added the Carrier and Service type.
Also, it's it confusing for hte consumer to have all those choices for the Service Type? And not all of them would apply for each Carrier type. Is there a best way to simplify the choices?
