disable two discounts in magento 1.8.1

Question

I created a Shopping Rule condition wherein my customers with products worth more than $50 in their cart is given 10% discount automatically.

Now, if the same user have a coupon code for 10% and he applies it, gets another 10% discount. This is a strict No.

I'm testing magento and wondering if anyone has a solution to add a condition to check the discounts be applied only once and not twice?

Answer 1
