HI ALL

I have a very big need ! I have this
combined function :

=AND(COUNT(B1;B2;B3)<=1;COUNT(C1;C2;C3)<=1;COUNT(D 1;D2;D3)<=1;COUNT(E1;E2;E3)<=1;COUNT(F1;F2;F3)<=1)

{ this function shows me if every of the 5 COUNT combined functions
in
AND function have the result <=1 (what I strongly need );
the problem is that I'll must do some few milions af this functions
with the reference in combinatoric order ,but this is not a
problem ,too,
(because I have a strategy to do this !) } .

what I need is a function to be eqivalent (!) to this (!!) function
posted here
(I'm shure I'll built easyer then my actually combined function ).

any sugestion will be more then wellcome
