REF: assigning discounts to categories of products

Hi Im having problems assigning DISCOUNTS to categories of products.

I need to add a discount so that if any product from category X is purchased a discount is applied, if 2 items are purchased (2 x discount is applied)...

At the moment Im getting "The discount code you entered is not valid" even when I cut and paste the code directly from the backend of the system into the front...
If I switch to this setup to a coupon the same code works.

Have attached a screenshot of my setup as a discount

Many thanks for getting back to me, might I ask if anyone else has reported finding that discount codes arent matching even when you cut and paste the code directly from the backend into the frontend cart? Im assuming if I assign a discount to a category any product within the category should allow the discount to be applied? At present when assigning a discount to a category, and then attempt to use the discount code I keep getting the message "The discount code you entered is not valid"

This relates to the image of the discount setup above

Many thanks

Kate

Thanks Nicholas, it makes sense now having compared the operation of the demo site really made me realise doesnt work in the way Id hoped. Back to the drawing board. Many thanks for reclarifying and your assistance.

Much appreciated

Kate
