Hi,
See below formula and snippet for reference - I want it all the same but the only thing i want adding is if the line is overdue then in the 'late booking?' column to show 'YES - OVERDUE SERVICE'
=IF(ISBLANK([Planned/Proposed Service Date]@row ), "", IF([Planned/Proposed Service Date]@row < TODAY(), "IN PAST - ACTION ASAP", IF(OR(MONTH([Planned/Proposed Service Date]@row ) <> MONTH([Due Date Of Next Inspection]@row ), YEAR([Planned/Proposed Service Date]@row ) <> YEAR([Due Date Of Next Inspection]@row )), IF([Planned/Proposed Service Date]@row > [Due Date Of Next Inspection]@row , "YES - OUTSIDE MONTH", "ETA EARLY - OUTSIDE MONTH"), IF([Planned/Proposed Service Date]@row > [Due Date Of Next Inspection]@row , "YES", "N/A"))))
