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 burl_rfc |

Try this
=SUMPRODUCT((I2:I4139="")*(D2:D4139=Y34)*(K2:K4139 =Y6)*(N2:N4139<=Y7)*(S2:S4139)) Mike "burl_h" wrote: I'm having a difficult time with the following sumproduct calculation.

Mike H,
Thanks it worked a treat. But why is the "*" working in this case, I've always used "," to separate the statements? Thanks burl_h |

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 http://www.xldynamic.com/ Mike "burl_h" wrote: Mike H, Thanks it worked a treat.

Sumproduct problem
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. -- If this helps, please click the Yes button Cheers, Shane Devenshire "burl_h" wrote: Mike H, Thanks it worked a treat.
