I am trying to have smartsheet calculate the difference between a start date and end date, but I will never have all dates in the sheet. I need it to return blanks when either start or end date is missing instead of #invalid data type.
Can someone please help? I already tried a conditional formatting rule to white out the #invalid data type text, that doesn't work, and several iterations of the "" I would usually use to return blanks in excel.
Thank you!!!!
