If Column A is dates for this year (1-1-05, 1-2-05,...) and column C is
values corresponding to those dates. How can I sum this months values only
(so that next month it will do the same without changing my sum range).

If it helps, I have the start and end day of the month in two cells...

Thanks for the help.

Take a look at the sumproduct formula...

This should work for you.

=sumif(A:A,"<="&EndDate,C:C)-Sumif(A:A,"<"&StartDate,C:C)

would be one way.

I figured it out based on other posts but I have no idea why this works....
=SUMPRODUCT((($A$9:$A$371='Sales Credit'!$P$31))*($A$9:$A$371<='Sales
Credit'!$P$32),'Sales ID'!C9:C371)
what does a sumproduct do?

Thanks for the replies.

Tom I assume your "enddate" could be a cell value...

Thanks again.

=SUMIF(A:A,""&TODAY()-DAY(TODAY()),B:B)-
SUMIF(A:A,""& 32+TODAY()-DAY(TODAY())-
DAY(32+TODAY()-DAY(TODAY())),B:B)

will always show the sum of "this month's" values.

The formula states "sum all the values in column B that correspond to dates
that are greater than the last day of the previous month; then subtract the sum
of all those values in column B that correspond to dates greater than the last
day of the current month".

Your formula works because in a computer True is 1 and False is 0 (not
exactly 100% true but good enough). So when you say

($A$9:$A$371='Sales Credit'!$P$31) you end up with an array of essentially
1's and 0's depending if the date is greater than or equal to 'Sales
Credit'!$P$31. The same is true of ($A$9:$A$371<='Sales Credit'!$P$32). 0
times anything is going to be zero. The * is equivalent to an and condion so
the date will have to be greater than the start date AND less than the end
date for the value in C to be included. The web address I posted might be a
little more clear on this point than I just was.

both enddate and start date are meant to be cell references

=sumif(A:A,"<="&M2,C:C)-Sumif(A:A,"<"&M1,C:C)

where M2 holds the end date and M1 holds the start date (for example)

You can go to the reference provided by Thomlinson, but be advised that
Sumproduct is slower than Sumif. Shouldn't be a perceptible difference in
your case.

I would have thought that 1 sumproduct would be faster than 2 sum if's. I
believe you, but what would the reason behind that be? Or is it just one of
those trueths that can be accepted at face value.
