hi, !

Your formulas return incorrect values for the problem.
Please see the previous post from T. Valko and my response to his post
as well as my previous response to yours.
I really appreciate your efforts and they have given me some additional ideas
to possibly help me with other problems, so thanks very much for that.

don't worry, "my" proposed formulae were made with assumptions on your data-type & arrangement
and i saw your response/s but, with Tony you are in the best hands (than mine)

if my "wild" ideas gives to you additional ideas (for other situations)... i'm glad for that
so, thanks to you (for your feed-back), i really appreciate it ;)

regards,
hector.
