I just recently installed shipstation and love it alot. However there is one important thing that I cannot use which is the packing slip function because the purchase order value is not passed.

1) How to edit shipstation_zc.php to pass super orders purchase order value?
2) Also I found something else that boggles me. When I just take the shipstation_zc.php and open and save in dreamweaver then reupload it errors in shipstation when I try to update orders from store. Yet I did not change anything. Here is the error code. However uploading default file shipstation works completely fine.
"An error occurred attempting to update orders: Invalid XML. Error: 'Name cannot begin with the '.' character, hexadecimal value 0x00. Line 1, position 2.' We received: '<?php
/*"

Thanks for any help in this. I am not a coder put tried to copy some of what is in file already without any luck. Maybe just because for some reason saving in dreamweaver does some bad things.
