Changed it to:
Code:
Private Sub txtStatementDate_AfterUpdate()
If Day([StatementDate]) <= 14 Then
[ServicePeriod] = DateSerial(Year([StatementDate]), Month([StatementDate]), 1)
Else
[ServicePeriod] = DateSerial(Year([StatementDate]), (Month([StatementDate]) + 1), 1)
End If
And it works great. I even tested it with December dates and it works as well. 12/16/13 Statement date resulted 01/2014 ServicePeriod.
I think it's safe to say now that this has been solved.
Thanks again for your help, it's greatly appreciated!!!!!!!
