I'd like to add a variable in the Order Receipt and Payment emails for “Amount Owing”.
This is the amount shown on the Admin Order screen.
  1. New Club Credit shows up as a payment right in the Cart. When the Order Receipt email is sent it doesn't acknowledge the partial payment. Including the Amount Owing would clarify.
  2. When a partial payment is made, the payment notification does indicate whether or not other partial payments have been made against the order. So a user may not know how much is outstanding. They could go to My Orders, but simply showing Amount Owing in the email would simplify the communication.
