date range
I want to calculate the number of times a ? is in one column (T) when the
date is less than 28/02/09 in column G. I have tried numerous formula, yet it either counts all the ?,s without taking into account the date or gives me a figure of 0. The examples of what I have used is =SUMPRODUCT(--('LTS Pipeline'!T$12:T$2000="?"),--('LTS Pipeline'!G$12:G$2000<="28-Feb-09")) Can anyone help!?!? Many thanks |

date range
You need to convert the date into a serial date
from =SUMPRODUCT(--('LTS Pipeline'!T$12:T$2000="?"),--('LTS Pipeline'!G$12:G$2000<="28-Feb-09")) to =SUMPRODUCT(--('LTS Pipeline'!T$12:T$2000="?"),--('LTS Pipeline'!G$12:G$2000<=DateValue("28-Feb-09"))) "RDC" wrote: I want to calculate the number of times a ? is in one column (T) when the date is less than 28/02/09 in column G.

date range
Try one of these:
=SUMPRODUCT(--('LTS Pipeline'!T$12:T$2000="?"),--('LTS Pipeline'!G$12:G$2000<=DATE(2009,2,28))) Better to use a cells to hold the criteria: A1 = ? B1 = 28/2/2009 =SUMPRODUCT(--('LTS Pipeline'!T$12:T$2000=A1),--('LTS Pipeline'!G$12:G$2000<=B1)) Note that if cells in 'LTS Pipeline'!G$12:G$2000 are empty they will evaluate to be less than 28/2/2009. If you need to account for that: =SUMPRODUCT(--('LTS Pipeline'!T$12:T$2000=A1),--('LTS Pipeline'!G$12:G$2000<""),--('LTS Pipeline'!G$12:G$2000<=B1)) -- Biff Microsoft Excel MVP "RDC" wrote in message ...
