You need to wrap your call to DMax in Nz, and set the return_if_null argument to a Long Integer that will never occur in REGSTAT32511.

What is the point of storing a number that is a copy of a number? If you want to know the numerical value of any date: Select myDateFld, myDateFld * 1 As numberValue from myTable; If you had entered both date and time in the myDateFld, then IntegerValue would in fact be a double precision number.
