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.
