[Done v1.3.9a] Double Discount Coupon message

[andy1234]

Hi All,

I am getting a double discount coupon congratulations message on the Step 2 of checkout (zen 1.3.8)

Congratulations you have redeemed the Discount Coupon
Congratulations you have redeemed the Discount Coupon

it loooks as either ot_coupon.php is called twice or writes two values to the $messageStack


Any ideas what could be wrong here?

Thanks

A
