Hi I have added this contribution. But I have a problem with Paypal Express Checkout. If i click the paypal checkout button it goes to paypal and then it bypasses the checkout_payment.php (where the discount code input is) and goes directly to order confirmation page. Therefore The customer cannot added the discount code and the discount is not used. However if i go throught the Oscom checkout the discount can be used. Is there a solution to this?
