Is it possible to combine several sumif's and then subtract it from a base number? Here is my best attempt.
=sum176-(SUMIF($B10:$AF10,"PD",$B11:$AF11)+SUMIF($B10:$AF10,"FA",$B11:$AF11)+SUMIF($B10:$AF10,"PS",$B11:$AF11)+SUMIF($B10:$AF10,"PN",$B11:$AF11)+SUMIF($B10:$AF10,"F1",$B11:$AF11)+SUMIF($B10:$AF10,"P1",$B11:$AF11)+SUMIF($B10:$AF10,"F7",$B11:$AF11))
=sum176-(SUMIF($B10:$AF10,"PD",$B11:$AF11)+SUMIF($B10:$AF10,"FA",$B11:$AF11)+SUMIF($B10:$AF10,"PS",$B11:$AF11)+SUMIF($B10:$AF10,"PN",$B11:$AF11)+SUMIF($B10:$AF10,"F1",$B11:$AF11)+SUMIF($B10:$AF10,"P1",$B11:$AF11)+SUMIF($B10:$AF10,"F7",$B11:$AF11))
