I only want to count the entries in column B is column F is suspect
but I don't want to count the same entry in column B twice. So in th
end I want the number of suspect TRS.

thanks,
Matthe

=SUM(--(FREQUENCY(IF((F2:F9="SUSPECT")*(B2:B9<>""),MATCH(B2:B9,B2:B9,0)),ROW(INDIRECT("1:"&ROWS(B2:B9)))-1)>0))

which you need to confirm with control+shift+enter instead of just wit
enter.
