Hello all

Whilst importing records from Mapmate, using Stuart Ball's Mapmate queries (generating mapmate keys and then using excel import wizard) resulted in a number of invalid records, as well as duplicated records, having previously imported some of these records before. The invalid records were picked up as "Determination Date can not come before the sample key". Has anyone come across this before? On tracking down these invalid records it turned out the the records were duplicates and not invalid, with the same date for both.
