Could you please tell us how many of this item and what colors you would like to order?这句话

how many the items and what colors you would like to order~我想表达的意思是 "您想订购多少这种产品" ,这里的产品只有一种,我就纠结要不要用of these items,但是我朋友说不要,所以我就迷惑了哦，可以这么问， Could you please tell us the quantity and what colors you would like to order? quantity是数量的意思。 当然你这句话也表达出你的意思了。
