Could you please give us a bit more details about what you are trying to do?
I presume that you would like to:
1. display coupon code if the price is over certain amount
2. accept coupon codes on your payment processing tool
3. automatically apply coupon code if over a certain amount
Do let us know if any of the above is true and if so which one.
