Adding coupon code

How would I apply a discount to the entire cart (Grand Total) not just the total price. I have other charges added after total price based on certain options but I need to apply the discount to the Grand Total

thank you.

since the grand total is calculated as :

(subtotal + shipping + tax + charges) - discounts

you cannot include the grand total in a discount rule, it would cause an endless loop. because the grand total would change every time the discount where applied.

however, set the discount rul cacluation to a flat rate of:
($this->GetTax() + $this->GetCharges() + $this->GetShipping() + $this->TotalColumn("TotalPrice")) * 0.1

where 0.1 is a 10 percent discount on

subtotal + shipping + tax

not including the discount.
