Payment method discount calculation incorrect

Hello everyone

Sorry to post this here...I have a problem with VM, but I don't get any response as there are too many posts...
If anyone using VM and can help me, it would be very much appreciated.

I have a problem with payment method discount.
I set 2% discount for direct debit and VM applies the payment method discount to the subtotal, not the total after coupon discount when there's a coupon discount.

For example,
Order subtotal :$59.50
Coupon discount : -$5.95
(subtotal $53.55)
Payment method discount : -$1.19 (should be $1.07)
Total : $52.36 (should be $52.48

The item subtotal is $59.50
and AW coupon discount 10% $5.95
and the total comes to $53.55 which is the amount customer has to pay.
Therefore, I want the payment method discount 2% to apply to the total $53.55 (2%=$1.07) not to $59.50 (2% = $1.19).
The difference is not that big, but when the coupon discount is a big one, it makes a lot different.

Could anyone please help me to correct this? I tried to modify the code, but no luck...


Thank you in advance!

Hi, the payment method discount is calculated in
www/administrator/components/com_virtuemart/classes/ps_checkout.php function get_payment_discount

Within that function, you could probably add something like this
