is it just the AN column array you are having problems with, or the full
equation?
try a
=sumproduct(--iserror([Data.xls]A!$AN$2:$AN$5000))
if you get a 1 try
=sumproduct(--iserror([Data.xls]A!$AN$2:$AN$5000),row(([Data.xls]A!$AN$2:$AN$5000))
if you get more that 1 try reducing the range until you do get 1

Greetings,
Im looking for an explanation for something happening in Excel that I dont
understand. In a worksheet cell I have a formula
€œ=SUMPRODUCT(--([Data.xls]A!$H$2:$H$5000=€�Asia€�),--([Data.xls]A!$AN$2:$AN$5000))€�
which works fine. Regardless of how I try to do it, I cant copy it to any
cell on any other worksheet without an error €œ#VALUE!€� rising from the
€œ--([Data.xls]A!$AN$2:$AN$5000))€� array. I dont understand why I get an
error when I know the formula works fine.
Appreciate whatever help you can give me!
Jim
