One way (array-entered):

=SUM((XXX!$CC$5:$CC$13390=0)*(XXX!$CB$5:$CB$13390= 0)*(XXX!$CA$5:$CA$13390
=0)*(XXX!$BZ$5:$BZ$13390=0)*(XXX!$BY$5:$BY$13390=0 )*
(XXX!$BX$5:$BX$13390<0))

I currently have an array function to sum revenues from a list of customers.
Is it possible to count the number of customer associated with these
revenues?

The formula I am using is:

{=SUM(XXX!$BX$5:$CC$13390*(XXX!$CC$5:$CC$13390=0)* (XXX!$CB$5:$CB$13390=0)*(XXX
!$CA$5:$CA$13390=0)*(XXX!$BZ$5:$BZ$13390=0)*(XXX!$ BY$5:$BY$13390=0)*(XXX!$BX$5
:$BX$13390<0))}

Thanks!
