If Century is set on, don't they have to enter a 4 digit year?

otherwise, are you looking for something like:

if Year(dtofBirth) > Year(date())
dtofBirth = ctod(alltrim(str(Month(dtofBirth))) + ;
alltrim(str(Day(dtofBirth))) + ;
alltrim(str(Year(dtofBirth)-100)))
endif

>A user can enter 2 or 4 digit value for the year section in a datetime field: (i.e. 01/01/01 or 01/01/2001)
>
>1. If the year is in the future, invalid - set to same date in previous century (i.e. 08 entered, make it 1908, or 2008 entered, make it 1908).
>2. If the year is between the current century and the current year (2000/00 to 2007/07), assume this century.
>3. If the year is greater than the current year, set it to the same date in the previous century.
