Hi John, Thanks for taking the time to respond. What am I trying to do? Well...I am trying to build a mailing list of previous customers WHO purchased product_id 1 but not product_id 14. I have the product items (id's) stored in the CartTable and I have customer info stored in the OrderTable. Using the same column of cart_id in both CartTable and OrderTable I am able to reference which cart items (id's) belong to each record in the OrderTable. What I did originally (that didn't work) was to select all records in the CartTable that matched product_id=1 and product_id!=14 then I used that information to reference against the OrderTable to grab the customer information I needed. The problem with my logic is that I did not take into account those who purchased one of the product_id's on ONE purchase and then came back the next day, week, year, etc and made another purchase for the other product_id which. I NEED to make sure that a customer HAS purchased product_id=1 and NOT product_id=14 at ANY time, regardless of a single or multiple orders. Does this make any sense? *sigh* Thanks again.
