Try this:

=IF(COUNTA(B1:C1),SUMPRODUCT(--(A$1:A$7=A1),--((B$1:B$7="yes")+(C$1:C$7="yes")0)),"")

Hi,

Data as follows:

A B C
ID1 YES YES
ID2 YES
ID3 YES
ID1
ID4 YES YES
ID2 YES
ID2 YES YES

What formula to be inserted in Column D to result the number of times an
ID
in Column A repeats in case where either Column B or C shows "YES"

Desired result:

A B C D
ID1 YES YES 1
ID2 YES 3
ID3 YES 1
ID1 "" (Blank because B & C both are <"YES")
ID4 YES YES 1
ID2 YES 3
ID2 YES YES 3
