Hey, 
I am using Oddo 15. 
I'm having an event and would like to send out coupons to some attendees so they can get free tickets. 

I have created a coupon that gives 100% discount on a product. 
Now when I book a ticket in the event and enter the coupon, the price jumps to 0,00€ and the payment functions disappear. Understandable :) 
The button "Confirm Order" appears instead. But the button "Confirm Order" does not work then and leads to a page with an error message. 

How can I solve this problem?
