Hi
I have the following formula working on a sheet but I am trying to
reference the same cell range in another workbook (lookup.xls) in the
same folder. How do I change the formula to achieve this please?.

=IF(ISERROR(INDEX($A$1:$L$9,SMALL(IF($A$1:$A$9=$A$ 11,ROW($A$1:$A
$9)),ROW(1:1)),12)),"",INDEX($A$1:$L$9,SMALL(IF($A $1:$A$9=$A$11,ROW($A
$1:$A$9)),ROW(1:1)),12))


Any help is greatly appreciated as I am up against a brick wall on
this one
