Ok, I'm not sure what I'm doing wrong. Here is my formula.
=LOOKUP(K10,'C:\Documents and Settings\All Users.HARTMANS\My
Documents\Anna''s Stuff\Breakdown sheet test\Excel Stuff\[Current
Backorders.xls]Backorder Rpt Summary ANNA'!$A:$A,'C:\Documents and
Settings\All Users.HARTMANS\My Documents\Anna''s Stuff\Breakdown sheet
test\Excel Stuff\[Current Backorders.xls]Backorder Rpt Summary
ANNA'!$C:$C)+IF(ISNA(K10))

Please let me know how I can change my formula to make it work. When I
enter variations of this formula the cell comes up blank, which is what I
want, but the cells that contain values that are correct are also turning
blank. If you need more information, please let me know.

Thank you for all your help!
