New Post: discount by category by quantity

Hi,
Thanks for the response, that is getting closer, now the issue I get is that the system is not using the quantity breaks but only applying the discount to a quantity of 1! which is not even an option.
so it is set up as:
promo 1: discount: 10% > role: cupcake company > group category: boys > qty range 2 - 2 (all other fields default)
promo 2: discount: 5% > role: cupcake company > group category: boys > qty range 3 - 3 (all other fields default)

allow multiple discount checked

result:
qty 1 > topper added to basket > price £3.70 > discount applied -£0.37
qty 2 > topper added to basket > price £3.70 > discount applied -none
qty 3 > topper added to basket > price £3.70 > discount applied -none

If i remove the category from the promo code set-up it works correctly

Is this a bug or have I set it up incorrectly or am i expecting too much?
