Hi Leon & thanks. It sure is complicated. Jim Lucas example did the trick very nicely (in my other post - "extract varying data from array with different formatting" but here I am learning about other ways & means. Redoing the arrays means redoing the queries :-( but I'll have a go at it if I'm to learn anything. I already have a ranking column set up but am not using it at the moment for the author display. Anyway, I have enough to keep my neurons busy for a while. Thanks.
