Any help greatfully received !!! If I have a list of data as below ( eg )
1/1/08 10
8/1/08 15
15/1/08 20
22/1/08 30
29/1/08 40

The list has 'dates' in column A and numbers in column B and will always be
in this format. How do I creata a formula that can add up column B total, but
for a certain group of dates - ie the total of B for dates between and
including 8/1/08 and 22/1/08. Obvioulsy I can expand the range, but thought
this the easiest example of what I am trying to achieve !!
Thanking anyone in advance.

Gilly,

There are a couple of ways and here's one

=SUMIF(A1:A10,"="&C1,B1:B10)-SUMIF(A1:A10,"="&D1,B1:B10)

Where C1 is the start date and D1 is the end date of your sum range

Hi,

Forgot to mention that Excel may try and be 'helpful' and format this
formula as a date. If it does reformat as general.

Here's a sumproduct version.

=SUMPRODUCT((A1:A10=C1)*(A1:A10<=D1)*(B1:B10))

for dates between and including 8/1/08 and 22/1/08.
=SUMIF(A1:A10,"="&C1,B1:B10)-SUMIF(A1:A10,"="&D1,B1:B10)

To include the boundary dates the 2nd SUMIF criteria should be ""&D1.
