Tks AAA. I agree with that.
In the lookup file, Item (I should have called it "group"), can have multiple products. ie, "a" would have a number of products (records) as would "x".
Now in F2, make "item" a repeating field and format it for a dropdown list from "Item" in lookup. Make "Product" a dropdown list from "product" in lookup (related to "Item" in F2).
I find that for the first line, all is ok but the second, even though I select a different item, the product dropdown still gives me a list based on the first line.
Any clues, Tks, bruce
