you need to add another column for discount as percentage. so that the discount can be by amount keyed in by merchant (already completed) and "Total" by percentage such as 10% of "Total".
also please fix the calculation error.
the correct formula should be
-Change = Total - discount - discount by percentage( to be created by you)-Boost pay-Cash paid
