I want to make the “best buy” app helping customers to find cheepest shops. Of course, when we look for the single products, piece of cake, columns are: PRODUCT, SHOP, PRICE and then the list with filterng the product and order increasing by price gives proper answer. But the challenge for me is when I want to have it also for different product baskets. E.g. I have: “Small basket” with milk, bread and butter “Medium basket” with the previous plus cookies and eggs. … Getting the choice small/medium basket is easy, but challenge is to get such output, e.g. for small basket: SMALL BASKET: 3 items SHOP A: 9,05 $ \> SHOP B: 10,25 $ \> Detail gives the list of items for this basket in specific shop! Challenging also for U? ---

With choice of the basket I got now using relation+lookup the following: SMAL BASKET: 3 ITEMS milk shop A 2,25 $ bread shop A 1,25 $ butter shop A 2,75 $ milk shop B 2,05 $ bread shop B 1,45 $ butter shop B 3,95 $ For me this is a great success, but now I am stuck for getting the subtotal lines for shops and not the detailed ones for products! Help!
