Hi,
I am trying to create a formula that will count the # of project that are ">90" days out and "<=90" days out, then also projects that are "<=-90" days past complete date and ">-90" days out but it is returning an error #INVALID DATA TYPE error for sheet summary field (see screenshot below).
I am using the "# of days to finish Date" column that is counting the days with the formula as follows: "=IF(Finish@row > TODAY(), NETWORKDAYS(TODAY(), Finish@row), -1 * NETWORKDAYS(Finish@row, TODAY()))"
Can anyone provide some insight as to why the sheet summary field is not counting the # of projects that meet the "=COUNTIF" criteria?
