I am trying to create a function that will calculate
information within a date range.

IE: How many new entries made between 1/1/04 - 3/31/04;
How many ____ entries made between 1/1/04 - 3/31/04 (the
blank would be filled by the column label). Does any one
know how I can do this?
 
Nikolatos,

Try something like

=SUMPRODUCT((A1:A100>=DATE(2004,1,1))*(A1:A100<=DATE(2004,3,31))

You could put the dates in cells and test against those cells

This is similar to needing a COOUNTIF function with two criteria. You can do this with a SUMPRODUCT. Assuming your dates are in A10 through A100, you can count the number of dates between two dates by entering the two dates in A1 and A2 and using the following formula

=SUMPRODUCT((A10:A100>=A1)*(A10:A100<=A2)

If you want to count the number of time Fred appears in column B between the above dates, then enter Fred in A3 and use

=SUMPRODUCT((A10:A100>=A1)*(A10:A100<=A2)*(B10:B100=A3)

Hopefully this gets you started

Good Luck
