# How to ignore blank date cells in sumproduct

#### Phil_S

I have a worksheet in which I am tring to sum the data based upon a code
range, a date range and cost range. However when I enter this formula it sums
the data from blank cells into the cell i wish to sum all the costs for
January.

=SUMPRODUCT(--(\$B\$2:\$B\$268=\$U277),--(MONTH(\$D\$2:\$D\$268)=8),(\$K\$2:\$K\$268))

Is there any way around this?

Hi,

I can't make that formula misbehave, it looks fine to me can you give the
precise circumstances under which you get an error.

Thanks for the reponse Mike.

I have...

CODE ORDER DATE COST
CS01 7-Jan-08 Â£200.00
MT03 14-Jan-08 Â£4000.00
MT03 (blank) Â£500.00

This is a shortened example

The formula is fine but my problem is when a cell in the date column is
blank it assumes that it is the 00-Jan-00 and totals up the data in my
January totals Table.

I would like it to ignore the blank cells. Is this Possible?

Check to see if there's something numeric in that D range:

=SUMPRODUCT(--(\$B\$2:\$B\$268=\$U277),
--(isnumber(\$d\$2:\$d\$268),
--(MONTH(\$D\$2:\$D\$268)=1),
(\$K\$2:\$K\$268))

Try this array formula

=SUM(IF((B2:B4=A1)*(LEN(TRIM(C2:C4))>0)*(ISNUMBER(C2:C4)*(MONTH(C2:C4)=1)),D24))
