Put the following in your TextChanged method of your textboxes. Set Textbox1.Text = CheckDates().

Function CheckDates
    'Checks to make sure dates were entered'
    If Not IsDate(Textbox2.text) or Not IsDate(Textbox3.text) Then
        Return "No Dates"
        Exit Function
    End If

    If CType(Textbox2.text,Date) >= #12/4/2010# and CType(Textbox3.text,Date) <= #1/1/2011# then
        Return "Submit"
    Else
        Return "No Dates"
    End If
End Function
