Applying the coupon discount before

I have a question about applying coupons. I have some coupons set and when I click the apply coupon button, is there a way to see the discount before they have to click the PayPal button?
I have attached two screen shots to see what is happening once I click the button.
As you can see, the price stays the same. The 'Gree' (Im a poor typer) button is actually a free 100% discount. Thanks so much for your speedy response! :slight_smile:
