Runtime Error message 94

Can anyone help with the following?
I am trying to use the MONTH function within the following procedure but I get an 'Invalid use of Null' error when [StartDate] is blank!

Private Sub StartDate_AfterUpdate()
Dim aMonth As Integer

aMonth = Month([StartDate])

If aMonth = 0 Then WOW = WOW
If aMonth = 1 Or aMonth = 2 Then WOW = 0.6
End Sub

Try using the Nz() function as follows

aMonth = Month(Nz(Me.StartDate,0))

Or

If Not IsNull(Me.StartDate) Then
    Date Found
    Do something here
Else
    No Date Found
    Do something here
End If
