Hi, I'm back again asking for some help.

I have in column A and B 2 formulas that evaluate to either true or
false. In column C I have a number. Say that I have 1000 rows; i want
to sum only those values in column C where valuels in column A and B
in the same row are both true.

Of course I can create a new column D where I AND booleans in A and B
but This would make me create a new column ... I do not want this
because in my file I have many many pairs of A & B. So I would have to
create at least 25 more columns containing AND formulas...

I need something that doesn't oblige me to create any new column

Thanks in advance for any help

Sorry for my english, I hope I have made myself understood.

Paolo

Italy
