Please pay attention for the formula input field.
The formula is:=IF(SUM(A21)>0,SUM((A21*E21)-F21),"")
This mean WHILE(Quantity > 0,SUM((Quantity*Price)-Discount)
From the customer level we can get amount of the quantity input field.
Obviously we set the price and optional discount.
So the formula works perfectly well because if the quantity from user is bigger than zero, the formula multiplies quantity by price of the product then subtract the discount amount to get amount to pay and display it during the checkout, finally charge the price for the product/ service.
