I've set up a formula that is correctly counting my data using 1 criteria; however, I'm ready to add a second and third criteria to my formula. How do I nest in my 2nd & 3rd if statement? The additional criteria I need to add is Data!B2:B10000=K2 and Data!A2:A10000=L5.
=SUMPRODUCT(--FREQUENCY(IF(Data!D2:D10000=K1,MATCH(Data!C2:C10000,0)),ROW(Data!C2:C10000)-ROW(Data!C2)+1)>0))
=SUMPRODUCT(--FREQUENCY(IF(Data!D2:D10000=K1,MATCH(Data!C2:C10000,0)),ROW(Data!C2:C10000)-ROW(Data!C2)+1)>0))
