Hi, Thanks for your answer.
Looks like I'm not doing the question clearly.
If you see the attached image it has Column "Hours" Column "Price", Column OT (Overtime), Column "OT Price" (Overtime Price) and Column "TOTAL"
Total = (Hours * Price) + (OT * OT Price)
I've bee able to create those columns in a new Invoice Template but I've been unable to use those new Two Columns to make calculations for the TOTAL (as formula shown above).
Is this formula possible adding those two columns on Premier 2020?
Have you an example?
