Hi Scott,

Thanks for this contribution~

I'm running 1.38 and stock by attributes. I had no issues installing the GW mod, and have merged my code. I have also installed the module via Admin/Modules/Order Totals.

On the shipping page (Step 1) - everything is good and well. I see the GW checkboxes (which i can check).
However, when I get to payment page (Step 2), the GW label + total are missing and not reflected in the order total.
From here if I complete the checkout - the invoice totals do not reflect GW. This is also the case when i check the orders via admin.

Any pointers to which code to look at?

Thanks.
