Hi,
I'm trying to use a Sumproduct or Countif that will find a certain criteria between specified dates.
By itself or within the same file, the function works well.
Now, trying to extract data from another file in which I'm not permitted to modify, I'm getting a "###" result, instead of a numerical value.
How could I modify the following or have a function that will give me desired results?
=SUMPRODUCT(--('[ABC.xlsx]Issue Tracking'!$F$4:$F$10000>=E21),--('[ABC.xlsx]Issue Tracking'!$F$4:$F$10000<=E27),--'[ABC.xlsx]Issue Tracking'!$L$4:$L$10000=$G$4)
E21 = 09/14/12
E27 = 09/27/12
G4 = XYZ
Thanks
