Trying to add a new 10% off on orders over £800 coupon to our site (v.1.7.0.2) and I keep getting the following message: "Coupon code "10off" is not valid."
If I remove the subtotal over 800 condition it applies fine.
Please can someone give me a clue why this might be happening?

Try to set the 'user per customer = 100 or blank'. I got the same problem before and it solve it.
