Trying to use a formula for autonumbering that will start over the fill number every year. Formula works well in a cell, but I can't get it to convert to a column formula
=IFERROR(RIGHT(YEAR(Date@row), 2) + RIGHT(COUNTIF(Date1:Date@row, YEAR(@cell) = YEAR(Date@row)) + 10000, 3), "")
Error message comes up that the column formula syntax isn't quite right, see our help article for more information
Any help would be appreciated!
