My apologies. It certainly was not meant to disparage the suggestion. I
had tried all sorts of counts as I mentioned before. I spend an awful
lot of time testing and trying but I'm afraid I don't really grasp all
the concepts involved. I am rather visually oriented and not seeing
things is rather frustrating.
I shouldn't assume so much and will certainly examine your suggestion
and learn where I went wrong.
Thanks again.
