Hi I am trying to calculate days but accounting for blank cells. If both blank do nothing, if both valued subtract. I got that part but trying concatenate with third option,,,, one has date other doesnt so i want to subtract from todays date. I think i am close, any help is appreciated. The aprt before the middle OR works
=IF(OR(ISBLANK(O5),ISBLANK(P5)),"",O5-P5 ) OR IF((ISBLANK(O5),P5="*")),Today() - P5,)
