So I'm using this formula to find the earliest date that isn't a blank out of a column, and when I only have one date that's in the column and is greater than or equal to today the formula returns the correct date or "No Project Scheduled" appropriately. However, when I have two or more dates that meet that same criteria the formula throws a #INVALID DATA TYPE error.
=IF(COUNTIF({Estimated Shoot Date}, >=TODAY()), MIN(COLLECT({Estimated Shoot Date}, {Estimated Shoot Date}, @cell <> "", {Estimated Shoot Date}, >=TODAY())), "No Project Scheduled")
