Hello all,
I have a need to find duplicates in a column where only the left four
characters match. I read through the posts and found the following formula
on Chip Pearson's website (thanks Chip), but have been unable to successfully
modify it to indicate when the left four characters match for the
concatenated text cells in the range.

Can anyone provide assistance?
Thanks for your help,
Bruce

=IF(MAX(COUNTIF(INDIRECT("c39:C"&(MAX((c39:c47<"" )*ROW(c39:c47)))),
INDIRECT("c39:c"&(MAX((c39:c47<"")*ROW(c39:c47))) )))1,"Duplicates","No
Duplicates")
