Discount Coupon issue

[vivek_web]

Hi,

I have installed discount coupon contribution 3.32 from oscommerce and using Oscommerce version 2.2.

When i complete the checkout_payment.php page process (payment details and discount coupon code), the page has been moved to checkout_confirmation.php page but there is no discount details appearing in billing information part. It shows only the sub-total, shipping cost and the total values.

When i refresh the page, the page displays the billing information with discount information.

If we confirm the order without refreshing the page, the billing details are properly stored in the admin's orders.php page with discount informations.

What is the problem? Please help me... Thanks in advance.
