Norie,
via VBA, I would use the current month and year to default to after the only day part has been entered.
This would be like the current functionality of being able to enter '5/25' and it adding the current year automatically to result '5/25/10'. I would just want to add the ability to auto fill the current year and month.
Have not had to deal with input masks other than the standards. What input mask would you recommend?
The datetime field does not like '25' being entered. I assume the validation for the field type is running before any 'AfterUpdate' event runs.
