Problem with Countif function to remove duplicates
Dear all,
I am trying to identify duplicates based on a unique string composed from multiple cells using the countif function. Now I encounter an issue where the incorrect value is returned for values that are clearly different from each other. In the attached file is the problem I am facing visible.
Can anyone help me with this issue?

Hey Ronald_Roos
Try This:
1) Insert a new column and enter this formula to extract the last digit of the number in column D as that is the number that changes:
=RIGHT(D2,1)
2) Then add the CountIF function to the column F. Hide column D if you want to

Use this formula in E2, and copy down rows:
=SUMPRODUCT(--(D$2:D2=D2))
By the way, your original formula works if you concatenate CHAR(173) before the criteria argument like this:
=COUNTIF(D$2:D2,
CHAR(173)&D2)The origin of the foregoing idea is from Lori Miller in this link:

See both formulas in the attached file.
