Category Selection Doesn't Save & Coupon Not Founc

Hi

I want to set up a coupon to give 20% off products in certain specified categories when the customer spends over £40. I have set AWO Coupon up with the following parameters:-

Function Type: Coupon
Function Type 2: Category
Percent or Amount: Percent
Discount Type: Specific
Value: 20
Minimum Value: Specific; 40

I have selected 6 categories but when I click save, the result shows "All Categories" selected.

When I try to use the coupon at the checkout, I get the error message, "Coupon code not found. Please try again."

Can you tell me what is going wrong, please?

Hello,

I am not sure. Can you turn on debug mode in global configuration and try it again? You might have a mysql error.
