Hello. I'm trying to combine the two formulas into one. I can break the
formulas into seperate parts; then calculate, but that adds 150+ cells.

SUMPRODUCT(('[abc.xlsx]2008 Mine'!G300:I400100)*('[abc.xlsx]2008
Mine'!G300:I400<=200))+SUMPRODUCT((G2:I40100)*(G2 :I40<=200)))/(COUNT('[abc.xlsx]2008 MIne'!G300:I400)+COUNT(G2:I40))

SUMPRODUCT(--(J11:J40="a"),--(D11:D40<=105),--(D11:D400)/COUNTIF(J11:J40,"a"))

Looking for % in the range of 100-200 in both sheets.

Thanks
