DISCLAIMER
Original Code is not owned by me ( it either comes from W3Schools or Murach’s SQL Server 2016 for Developer book
Augmented code is a combination of original source code and changes or additions made by me :….
these changes may be completely original or sometimes they are a combination of ideas and examples that come from the book

NOTE: InvoiceTotal-PaymentTotal-CreditTotal is a repeated statement that represents balance due, and this expression will be used many times, it is used by the book repetitively and will be used by me when I augment my code . The code is from page 91 of the book
