Hi,
I have three columns. One containing a "value" taken from a list,
another an amount and the third column contains a date.

What I need to do is for a particular value, find out the sum of all
the amounts for a particular month.

This is the formula I have written but the sum is not being calculated
for the particular date range.

Column D Column E Column F
15 March, 2005 23344 UK Perdiem
17 March, 2005 739874 UK Perdiem

=SUMPRODUCT((F5:F150)*(I5:I150="UK Perdiem")*(D5:D150= "15 March,
2005" & D5:D150<= "31 March, 2005"))

The value shows 0 but if I remove the date calculation it works fine.

Can anybody please help me with the formula?

Thanks in advance


=SUMPRODUCT($F$5:$F$150,($I$5:$I$150="UK Perdiem")+0,($D$5:$D$150=
"15-Mar-05"+0)+0, ($D$5:$D$150<= "31-Mar-05"+0)+0)

[1] The SumProduct function should implicitly coerce the truth values to
their Excel numeric equivalents.
[2] The lookup functions should have an optional argument for the return
value, defaulting to #N/A in its absence.
