That technique will work. But, by using IF this makes the formula an array
formula so your not getting any advantage in using SUMPRODUCT.

=SUM(IF(ISTEXT(A1:A5),IF(A1:A5=D2,IF(B1:B5<=N2,C1: C5))))

Mia culpa; thanks for checking it.

I tested a simplified equation, that when I look at it now was very wrong.
I like your method but got stuborn and tried a different version
new try
again beacause of AE having #N/As

=sumproduct(if(iserror('Retail 2006'!$AE$2:$AE$4000=$D$2),0,if('Retail
2006'!$AE$2:$AE$4000=$D$2),1,0),--('Retail
2006'!$C$2:$C$4000<=$N$2),'Retail
2006'!$F$2:$F$4000)
etered as an array control-shift-enter
unless I have made another typo.

Did you test that formula?

Aside from the syntax error it still won't work:

('Retail 2006'!$AE$2:$AE$4000=$D$2)

That array will still fail on any errors.

I tried to respond yesterday, but got one of those "No such site

try
=SUMPRODUCT(--not(iserror('Retail 2006'!$AE$2:$AE$4000=$D$2),('Retail
2006'!$AE$2:$AE$4000=$D$2)*('Retail 2006'!$C$2:$C$4000<=$N$2),'Retail
2006'!$F$2:$F$4000)

This is not practicable because:
a) The data worksheet is an import from a text file which is regularly
refreshed
b) The formula referring to column C specifies less than or equal to
the
value in N2 (for YTD sales)

Something else - column AE is the last column of data in Retai 2006
and
is
VLOOKUP formulae (the rest of the data is values). There are #N/A
values
in
this column.

on your retail 2006 sheet select all

in column AE filter select
custom type in the value for D$2
in column C filter select custom type in the value for N2
check column F for a #NA

The following formula is returning the #N/A error:

=SUMPRODUCT(('Retail 2006'!$AE$2:$AE$4000=$D$2)*('Retail
2006'!$C$2:$C$4000<=$N$2),'Retail 2006'!$F$2:$F$4000)

The following formula in other worksheets in the same file is
working:

=SUMPRODUCT(('Retail 2006'!$E$2:$E$4000=$D$2)*('Retail
2006'!$C$2:$C$4000<=$N$2),'Retail 2006'!$F$2:$F$4000)

The only difference is the first argument, which is referring to a
column
containing store types (Department Stores, Chains etc.) in the
worksheet that
isn't working and store codes (C10, C20, C30 etc.) in the one that
is. Cell
formats are set to general for both columns.

For your information:

Column C contains months of the year

Column F contains sales

Cells D2 & N2 are linked to combo boxes and display the Store Type
and Month
respectively. Again, cell formats are General.

What could be going wrong?
