In a calculated column, I'm trying to return a date for the column value. If the old reporting date is blank, then I am returning the last modified date.
Here's the code:
=IF(ISBLANK([Old Reporting Date]),DATE(YEAR(Modified),MONTH(Modified),1)-1,[Old Reporting Date])
If the old reporting date is blank, instead of returning the Modified date, the column returns a "3"...which is a total error.
Please help.
