Is there a way to make a sumifs formula that still works if one of the criteria is blank in some cases.
=SUMIFS('Indirect Rate Plan Analysis'!$F:$F,'Indirect Rate Plan Analysis'!$D:$D,$D17,'Indirect Rate Plan Analysis'!$L:$L,$C17,'Indirect Rate Plan Analysis'!$G:$G,E$15)
Sometimes C17 is blank
Thanks
