Display of Previous Due Amount on Invoice

Requirement:
To dynamically display three types of due information on the invoice:

1. Today's Due on Current Sale: The amount due for today's sale transaction.

2. Previous Due on Total Sales: The sum of all outstanding dues from previous sales.

3. Current Due Total on Total Sales: The total amount due, combining both today's due and all previous dues.

Current Status:
Currently, only two types of due information are shown on the invoice. The goal is to update the invoice to dynamically display all three due amounts.
