Hello,

I'm looking for a function that can:

TRUE every unique value,
FALSE if there is "Cancelled" in the same row column C
FALSE all of the duplicates, but mark the last duplicate with TRUE.

Thank you very much for your time and help!Screenshot-2023-01-14-at-12.21.50-1.png

In cell B1 enter :

=IF(C1="Cancelled","False",IF(COUNTIFS(A1:$A$13,A1,C1:$C$13,""&"Cancelled")=1,"True","False"))
