It appears that the unit price is the BASE PRICE with quantity discount (24-143) $9.47 + UPCHARGE Black $5.07 (1-23).

I was hoping that the BLACK option would take into account the total number of items, but it appears to be based only on the quantity of that particular item and the quantity of the individual items in the sample order above all fall into the (1-23 +$5.07). I have the attributes qty discount setup as seen below.

Attributes Qty Price Discount:
23:5.07,143:4.31,287:4.00,288:3.72

PLEASE LET ME KNOW IF THIS IS STANDARD ZENCART BEHAVIOR OF IF THERE IS SOMETHING I CAN DO TO SET THE BLACK OPTION TO USE THE TOTAL QTY (IF ALL ARE BLACK) SO IN THIS CASE IT WOULD ADD +$4.31 - UNIT PRICE $13.78
