I am attempting to count how many times there is a number greater than zero
in either column A or column B.

My goal is if A=0 and B=0, do not count. If A=0 and B=1, count. If A=1 and
B=1, count only once.

Thank you for any help

One way:

=sumproduct(--((A1:A100)+(B1:B100)0))

The "+" functions as "OR" in this context. The OR function cannot be used
in this context; it will not be interpreted as intended. The "--" (double
negation) is used to convert the truth values (TRUE and FALSE) to numeric
values (1 and 0), which SUMPRODUCT looks for. Any arithmetic operation with
truth values will accomplish the same thing.

What about something like this...

=COUNTIF(A1:A99,"0")+COUNTIF(B1:B99,"0")

Rick, does that meet that OP's condition that "[if] A=1 and B=1, count only
once"?

Here's another one...

=SUMPRODUCT(SIGN((A1:A1000)+(B1:B1000)))

This version is slightly more efficient on larger ranges.

No, it doesn't... I skimmed the OP's question too fast and completely missed
that requirement. Thanks for pointing it out.
