Sum between two dates but left blank if there is no date in one of the columns
I am looking for the formula to find the number of days it took between two dates only if there is a date added in Column A.
I have used and this worked great to get the days but if there are any blanks in Column A it comes back as a 0 and I am looking for it to be blank instead.
What do I need to add to make it blank if there is no date in column A?
=SUM([Column A]@row - [Column B]@row)
