So, I'm in responsehandler.php doing a little debugging, and this is what I have found.

I am writitng all the values that are returned to the error log like this:
error_func($cust_id);
error_func($data[$root]['buyer-shipping-address']['company-name']);
error_func($data[$root]['buyer-shipping-address']['contact-name']);
error_func($data[$root]['buyer-shipping-address']['address1']);
error_func($data[$root]['buyer-shipping-address']['address2']);
error_func($data[$root]['buyer-shipping-address']['postal-code']);
error_func($data[$root]['buyer-shipping-address']['city']);
error_func($data[$root]['buyer-shipping-address']['region']);
error_func("\n Zone zone id \n" . $zone_answer['zone_id']);

This is what I get back in my error log:
Sat Oct 14 0:39:07 EDT 2006:- 94
Sat Oct 14 0:39:07 EDT 2006:-
Sat Oct 14 0:39:07 EDT 2006:- John Doe
Sat Oct 14 0:39:07 EDT 2006:- 64 My street address
Sat Oct 14 0:39:07 EDT 2006:-
Sat Oct 14 0:39:07 EDT 2006:- 37343
Sat Oct 14 0:39:07 EDT 2006:- Chattavegas
Sat Oct 14 0:39:07 EDT 2006:- TN



It just completely dies when I get to the zone information. I am using the Table Rate on shipping. Is anyone else using table rate?
