i am develop my promotion addon bonus is : Order discount by fixed
its working well but when customer place order from different vendors. cs-cart doesnt calculate sub orders discounts. then doesnt show discount with orders details.
if order is come from one seller working without problem
?
i double check promotions.fn
fn_promotions_calculate_order_discount in this function
if (empty($cart['parent_order_id'])) {
HERE is put parent order promotion infos
but after else doesnt do any action ?
what should I pay attention to ?
