I'm sorry; I wasn't clear.

The SUMPRODUCT structure you'll need will
be dependent on the kind of data you are
testing and the kind of test you want to do.

Are we testing if each corresponding cell in Col_Z:
.. is a number?
.. is a specific number?
.. is text?
.. is specific text?
.. matches an item in a list?
Example:
Multiply each cell in X1:X100
by each corresponding cell in Y1:Y100
if the corresponding cell in Z1:Z100
does not equal "Canceled".

or..are we testing if any of the above
conditions exist anywhere in Col_Z?
Example:
Multiply each cell in X1:X100
by each corresponding cell in Y1:Y100
BUT only if "Canceled" does NOT exist
anywhere in Z1:Z100

In the meantime, perhaps this kind of structu
=SUMPRODUCT(--(Z1:Z100<"CANCELED"),--(X1:X100),--(Y1:Y100))

I've been trying to sum multiple columns where a condition does not
exeist in one of the columns. Example: columns x, y & z where z doesn't
contain "this condition".

I can understand that these work:
=SUMPRODUCT((condition1)*(condition2)*(condition3) )
and even =SUMPRODUCT(--(condition1),--(condition2),--(condition3))
but I can't understand how to get to my desired results. Would I write
the formula like this?
=SUMPRODUCT((condition1)*(condition2)-(condition3))
=SUMPRODUCT(--(condition1),--(condition2),-(condition3))

TIA


Thanks for getting back to me. Yes, (condition 3) is not in column z.
TIA
