Ok,

Same version 1.4 beta1. I am now trying to use OT (order total) based coupons.

I created a simple $5 discount coupon in my "Coupon Admin" page in the admin page, and tried to use it at the google checkout page, but the following message appeared:

Invalid coupon code
Retry
Your promotion code (5DDSC1) could not be applied at this time.
Some more info:
I just have two shipping modules active and connected to google checkout:
1. Item = standard shipping
2. Item2 = express shipping
No real time type module installed

What should I do to get the coupons working?

Thanks
