Coupon codes don't work

[redditor80]

Hi all,

I'm using Zen Cart with the AlertPay payment module.
Whenever a customer uses a coupon, it takes it off of the zencart total just fine, however, when they're forwarded over to the AlertPay payment page, the order shows as the original, pre-coupon amount.

Any ideas?

Thanks for your time!

Here the solution . allow to work with coupons and discounts
and send the shipping information to Alertpay
