I'm not convinced you are selecting the right items. At the point where you use refer to @itemid in your key(), the context has changed (you are inside a predicate) .. try replacing @itemid there with a variable that you set outside, as you did with $this_lists_items. Understand that until Jeni Tennison sees this thread, you can't expect a detailed, thoroughly tested reply with all the code you need to solve your problem :) - Mike ____________________________________________________________________ Mike J.
