Excel formula to extract unique values based on conditions

Hi all

I want to extract unique values based on conditions and put the result in a new cell.

In the attached workbook (tab : data) I would like to extract a unique area for each grower,block,section & year.
I want this result in the first line in and 0 in the rest where the conditions are met. See tab: desired result.

I am using Excel 2019.

Thank you in advance.

Regards

In "Data" sheet F2, copied down :

=IF(COUNTIFS(A$1:A2,A2,B$1:B2,B2,C$1:C2,C2,D$1:D2,D2,E$1:E2,E2)=1,E2,0)
