SUMIF when checking two columns.

Morning,

Any help would be greatly appreciated, thanks...

I'm using: =SUMIF($I$2:$I$249,"s", AC$2:AC$249) to add up the value in AC if there is an S in column I.

I now want to amend this to only add up the values in column AC if there is an S in column I and a M in column B.

Thanks

Use the formula somproduct for that.

Using 2010 SUMIFS will also do the trick

Try this one.

=sumproduct(($I$2:$I$249="s")*($b$2:$b$249="b")*( AC$2:AC$249))

Hi

As you are in Excel 2010 you can use.

1)=SUMIFS(AC:AC,B:B,"B",I:I,"S")

2) =AVERAGEIFS(AC:AC,B:B,"M",I:I,"S")
