Can someone please help on the below formula - it is not working and showing as incorrect argument - I want it to take into consideration both the month and the year - if it past or later than the proposed service date then i want it to show its late via 'YES', blank if its blank and if its in date to show as N/A - the column this formula is in is called 'Late Booking?'
=IF(ISBLANK([Planned/Proposed Service Date]@row ), "", IF(MONTH(YEAR([Planned/Proposed Service Date]@row ) > (MONTH(YEAR([Due Date Of Next Inspection]@row ), "YES", IF([Planned/Proposed Service Date]@row <> [Due Date Of Next Inspection]@row , "N/A"))))))
