SUMPRODUCT, INDIRECT, dates...

[LongTermNoob]

Hi,

I recently asked for help looking up values in one column by the year in
another column on different worksheets, and was very kindly given the
following solution:

=SUMPRODUCT(--(YEAR(INDIRECT("'"&A3&"'!H8:H1000"))=2008),INDIRECT("'"&A3&"'!I8:I1000"))

I have now been asked to add sub-totals by month! I came up with:

=SUMPRODUCT(AND(--(YEAR(INDIRECT("'"&A3&"'!H8:H1000"))=2008),(--(MONTH(INDIRECT("'"&A3&"'!H8:H1000"))=1))),INDIRECT("'"&A3&"'!I8:I1000"))

however this returns a #VALUE! error. I have also tried JANUARY instead of 1
for the month criteria - same result.

If anyone could help me on this I would be very grateful. TIA.

Try something like this:

=SUMPRODUCT(--(TEXT(INDIRECT("'"&A3&"'!H8:H1000"),"yyyy/m")="2008/1"),INDIRECT("'"&A3&"'!I8:I1000"))

Thanks, Biff, this works a treat!

Out of curiosity, is there any reason I couldn't do it with the AND
statement? Or does it just make things too complicated?

Thanks again,
Roger

You could also do it this way:

=SUMPRODUCT(--(YEAR(INDIRECT("'"&A3&"'!H8:H1000"))=2008),--(MONTH(INDIRECT("'"&A3&"'!H8:H1000"))=1),INDIRECT("'"&A3&"'!I8:I1000")

The formula I suggested is a bit shorter.

Excellent. Many thanks again...
