Behind the fields AfterUpdate command try this code (adapted to your form)
Private Sub InitialDate_AfterUpdate()
SixMonthDate = DateSerial(DatePart("yyyy",InitialDate), DatePart("m", InitialDate) + 6, DatePart("d", InitialDate))
OneYearDate = DateSerial(DatePart("yyyy",InitialDate)+1, DatePart("m", InitialDate), DatePart("d", InitialDate))
End Sub
All this code does is break down the date into seperate parts d/m/y and adds on the number you require to whichever part.
