To use the discount coupon code multiple times, you have to set the number available in Catalog > Discount Coupons. this will enable a coupon that can be used multiple times.
About my problem:
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.
Example:
Sub-Total: $11.00
Table Rate (Best Way): $7.90
Total: $18.90
When i refresh the page or navigate to other page and come back, it displays the billing information with discount information.
Example:
Sub-Total: $11.00
Discount Coupon FQRLY applied: -$1.10
Table Rate (Best Way): $7.90
Total: $17.80
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 will be the problem?
