The COD fee is an Order Total Module that displays the fee on the checkout_confirmation page as you have to select COD as the Payment module then hit Continue ...
If you were to be on checkout_confirmation and you see the COD fee ... then if you went back to checkout_shipping ... checkout_payment ... you would see it in the totals as it now knows that you have selected COD previously ...



The thing now is even when setting COD Fee to true it does not show in checkout. This is the original COD module from zencart 1.3.7. Do i need to configure zone rates?
Its ok I will try.
I manage to get the COD listed with the statement "COD fee maybe included" in checkout.
