Creating a Order Total Module

[kwright]

Greetings,

I'v been working on a new Order Total module and looking at the ot_gv code as a guide and been modifying and rewriting the gift card orders total code addon.

My questions is that I can't seen to figure out how and where to add the code such that the module name / method shows on the invoice and the Payment/Shipping column on the admin orders page when it is used to cover the order balance? Currently, the GV name/method shows even though I'm not using it?

I could update the GV defines here to what I want them to say:

  define('PAYMENT_METHOD_GV', 'Gift Certificate/Coupon');
  define('PAYMENT_MODULE_GV', 'GV/DC');

But that isn't the proper way to do it I'm sure!

Suggestions?

Thanks
