Mark,

Try this :
=SUMPRODUCT(
--(TEXT($W$24:$W$33024,"MM.YYYY")=TEXT(TODAY(),"MM.Y YYY")),
--($AU$24:$AU$33024<=25),
--(ISNUMBER($AU$24:$AU$33024))
)

No need to check for blank dates as this uses the text date.
But need to check for blank days.

Hope this helps

Hi,
I'm really struggling to get the following thing working, basically
because nothing seems to like uk date formats.

Anyway, I have a column with dates in (uk format!), called finish, and
another column with numbers (time in days) in.

I want to calculate the number of rows with a finish date in a certain
month and a time of less than 25 (days). The finish date may be blank,
in which case I want to ignore these.

Currently I have ( as one of my many possibilities):

=SUM(($W$24:$W$33024<"")*(DATEDIF($W$24:$W
$33024,DATE(YEAR(TODAY()),MONTH(TODAY())-3,1),"m")=0)*($AU$24:$AU
$33024<=25)*1)

The 3 is just an example of the number of months I want to go back
from today

Thanks for any help.

Can I just ask why you have "--" in this formula?
