Coupon discounting when it's not supposed to

Subversion: f

I created a coupon for an specific product. So top is as "deny" and the only product valid to use the coupon was added as allowed. The coupon is coming up correctly when you check it on the coupon lookup:

But when I test it to see if it doesn't work with another product, the system accepts the coupon and do the discount to the order.

Using One-Page checkout.

Do I have to put another "deny" on the category of the product? I thought that having "top" as deny, it was denying ALL the categories. I've done coupons on Zen Cart for 15 years without issues (for me and customers), and they work, :huh: please let me know why isn't working now as usual.

I think it was a "session" problem... But even though now is not accepting the coupon for that product, it's saying the wrong reason why is not accepting. It's saying: "You must spend at least $92.00 to redeem this coupon" when the real reason is the product, not the amount spent.
