Sumproduct problem
 

I'm having a difficult time with the following sumproduct calculation.

The main problem is that I want to sum all cells in column S, that do
not have a value present in the corresponding row in column I. Column
I is sparely populated with some values, the majority of column I has
empty cells. But it's very important that I only calculate column S
where no value is present in column I.

Column D contains names that match cell Y34, column K and N are start
and end dates.

=IF($I$2:$I$4139<"",0,SUMPRODUCT(--($D$2:$D$4139=Y34)*($S$2:$S
$4139),--($K$2:$K$4139=$Y$6),--($N$2:$N$4139<=$Y$7)))

Any help would be greatly appreciated.

Thanks

Try this

=SUMPRODUCT((I2:I4139="")*(D2:D4139=Y34)*(K2:K4139 =Y6)*(N2:N4139<=Y7)*(S2:S4139))

Mike H,

Thanks it worked a treat.

But why is the "*" working in this case, I've always used "," to
separate the statements?

Thanks

Hi,

It's just an alternative syntax for sumproduct, both have their uses.

the website seems to be having problems at the moment but have a look here
for help on sumproduct

Hi,

The other syntax will work just as well and there are times when, with a
slight modification, it would prevent a problem that the * syntax would
generate. So this is equivalent:

=SUMPRODUCT(I$2:I$4139="",D$2:D$4139=Y34,K$2:K$413 9=Y$6,N$2:N$4139<=Y$7,S$2:S$4139)

as is this, which is slightly safer in some cases:

=SUMPRODUCT(--(I$2:I$4139=""),--(D$2:D$4139=Y34),--(K$2:K$4139=Y$6),--(N$2:N$4139<=Y$7),S$2:S$4139)


Minor points, in both syntaxes you can drop the final ()'s as shown above.
If you are copying downward you only need absolutes ($) in front of the row
numbers.
