We have the following process:
- Customer made reservation and pays part of the amount due.
For example: order for $100, Customer pays $40.
- Administrator adds the payment at the back office. System calculates that the amount due for the order is now $60.
3, Admin changes the order's status to "partially paid".
We have configuration in the order statuses that upon changing the status "partially paid", system sends an email.
The question is: what parameter (if any) can be used in the email template if we want to show the customer that $60 are still due.
