I don't know about SUMIFS because I don't have Excel 2007, but you
can't use SUMIF with an external closed file, and I suspect that is
why you are getting #VALUE.

When an external file is open, Excel only needs to have '[filename.xls]
Sheet_name'!cell_ref to be able to reference a cell, but if it is
closed then it needs the full path to the filename as well - this is
why your formula has suddenly expanded.

Can you not arrange to have the Program Tracker file open at the same
time?

Hope this helps.

I should explain better... *HEre is what one of my cell formulas looked like
when it was first created:

=SUMIFS('[Program Tracker.xlsm]Detail'!$M:$M,'[Program
Tracker.xlsm]Detail'!$A:$A,"="&$D$6,'[Program
Tracker.xlsm]Detail'!$O:$O,"=No",'[Program
Tracker.xlsm]Detail'!$F:$F,"="&$C30,'[Program
Tracker.xlsm]Detail'!$U:$U,""&$D$2,'[Program
Tracker.xlsm]Detail'!$U:$U,"<="&$D$3)

Here is what it looked like after I saved the first file, then re-opened it:

=SUMIFS('C:\Documents and Settings\pklocke\My Documents\01-IT
Optimization\Planning\[Program Tracker.xlsm]Detail'!$M:$M,'C:\Documents and
Settings\pklocke\My Documents\01-IT Optimization\Planning\[Program
Tracker.xlsm]Detail'!$A:$A,"="&$D$6,'C:\Documents and Settings\pklocke\My
Documents\01-IT Optimization\Planning\[Program
Tracker.xlsm]Detail'!$O:$O,"=No",'C:\Documents and Settings\pklocke\My
Documents\01-IT Optimization\Planning\[Program
Tracker.xlsm]Detail'!$F:$F,"="&$C30,'C:\Documents and Settings\pklocke\My
Documents\01-IT Optimization\Planning\[Program
Tracker.xlsm]Detail'!$U:$U,""&$D$2,'C:\Documents and Settings\pklocke\My
Documents\01-IT Optimization\Planning\[Program
Tracker.xlsm]Detail'!$U:$U,"<="&$D$3)

Figured a "picture" might explain better than I did...thanks!
