I have about 150 cells With this formula. It seems this makes Excel use a lot of processor Power to calculate. Is there anyway to make it simpler? I mean, is it possible to split it ut and use another spreadsheet to make a partial calculation. Would that help?
=SUM(IF(FREQUENCY(IF('Timer spørring ekstern'!$W:$W=B1,MATCH('Timer spørring ekstern'!$C:$C,'Timer spørring ekstern'!$C:$C,0)),ROW('Timer spørring ekstern'!$C:$C)-MIN(ROW('Timer spørring ekstern'!$C:$C))+1),1))
