I am trying to add columns Z+AC+AL if column O falls within a date range of
01-Apr-09 to 30-Jun-09. I am transferring it to another worksheet. My
equation now is:

=SUMPRODUCT(--'[ADR Statistics -
template.xls]Region!$O$3:$O$31=M1)--('[ADR Statistics - template.xls]
Region!$O$3:$O$31<=N1)*('[ADR Statistics - template.xls]
Region!$Z$3:$Z$31+'[ADR Statistics - template.xls]
Region!$AC$3:$AC$31+'[ADR Statistics - template.xls] Region!$AL$3:$AL$31)

It is returning an answer of €˜60, ignoring the Apr 1, 2009 date.
(To make this sort of work, I removed a couple of "," and added an * to your
solution.)

Put the dates to be tested into cells (K3 and L3)
Then use
=SUMPRODUCT(--(O3:O8=K3),--(O3:O8<=L3),(Z3:Z8+AC3:AC8+AI3:AI8))

If it references another book it will look like
=SUMPRODUCT(--([MonthList.xlsx]Sheet3!O3:O8=A1),--([MonthList.xlsx]Sheet3!O3:O8<=B1,([MonthList.xlsx]Sheet3!Z3:Z8+[MonthList.xlsx]Sheet3!AC3:AC8+[MonthList.xlsx]Sheet3!AI3:AI8))
Where A1 and B1 hold the dates

I try never to 'hardcode' dates, but if I have to then I use this method:
=SUMPRODUCT(--([MonthList.xlsx]Sheet3!O3:O8=Date(2009,4,1)...... rather
than any specific date format

I am trying to add columns Z+AC+AL if column O falls within a date range

equation is:

=SUMPRODUCT((--'[ADR Statistics -

Region'!$AC$3:$AC$8+'[ADR Statistics - template.xls] Region'!$AL$3:$AL$8))

but it is returning a different number than expected.
Thanks, Lynn
