Button add coupon with 2 coupons not working

I have free shipping coupon. It works and it shows on checkout.

If I enter another coupon (for some discount on product) and click on button, nothing hapens.

If I click on delete first coupon, ajax refreshes and I can add second coupon.

Thanks for reporting.  This was an issue with AwoCoupon.  Since I have access to your site, I have fixed it.  And it will be part of all future updates.

Yes, now working. Thank you. Great support.
