edit usps shipping module -- help needed

[RixStix]

Not using ShipWorks but I'll give it a try.

What database table and what datafield does ShipWorks download for shipping?
The reason I ask is that our database does not save the number of boxes, nor weight in the Orders table => Shipping_method field.

ShipStation uses the shipping_method field to trigger their internal automation filters and rules. Maybe ShipWorks uses a different field or maybe zencart is saving the number of boxes and weight in the shipping_method field and turning that off will resolve your issue?

These are examples of what is in my shipping_method field. If you had that, it sounds like your problem would be resolved since the data needed is within the first 50 characters.
