Yet each has a perfect match on length. Equally clearly the next 2 choices are useless, even though each has a perfect match on both length an height. So the only reasonable choice is the last one, even though none of its dimensions is a perfect match. You see my point? THERE IS NO POINT in looking for a perfect match as a separate operation. What you really want is, as I suggested, the CLOSEST match on all 3 dimensions. But, again, you have to tell us what CLOSEST then means. Is it the sum of the differences being closest to zero? The product of the differences being closest to zero? What? __________________ An optimist sees the glass as half full. A pessimist sees the glass as half empty.
