#UNPARSEABLE error on my date using parent/child relationship

Options

What is wrong with my formula for parent/child relation?


=IF((COUNT(CHILDREN(Start Date@row))) > 0, INDEX(CHILDREN(Start Date@row), 1), "")


All other columns are working fine except for my dates.

    @Leighmercado you definitely have to have the brackets if you include the column name. Invalid column value is because you are putting a date in a non date column.

    To get around this error, you can add a "" to the end of the formula, like this:

    =IF(COUNT(CHILDREN([Start Date]@row)) > 0, INDEX(CHILDREN([Start Date]@row), 1), "")+""

    You could also reduce your formula to this:

    =IFERROR(INDEX(CHILDREN([Start Date]@row), 1), "") + ""
