Sorting Dates by Clicking Header/Label on a continuous form

In my Access 2000 app I have a continuous form with three columns 'TicketNo', 'TicketDate' and 'Status'.  The labels for each of these columns in the form header are 'TicketNo_Label', 'TicketDate_Label' and 'Status_Label'.  I have logic in the 'click' event of each of the respective headers.  The logic is intended to sort the data in the column that has been clicked.  If the data is already in ascending sequence it should be sorted to descending sequence.  The logic is the same for all three field labels and it works perfectly for 'TicketNo' and 'Status' which are Strings.  The logic does nothing to sort the 'TicketDate' field which is a date.

How do I need to modify the following code to sort the date field?

Private Sub TicketDate_Label_Click()
If Me.OrderBy = "TicketDate DESC" Then
    Me.OrderBy = "TicketDate"
Else
    Me.OrderBy = "TicketDate DESC"
End If
Me.OrderByOn = True
End Sub

For reference, the following logic which is exactly the same except for the field name, works perfectly on the other two fields:

Private Sub Status_Label_Click() '
If Me.OrderBy = "Status DESC" Then
    Me.OrderBy = "Status"
Else
    Me.OrderBy = "Status DESC"
End If
Me.OrderByOn = True
End Sub

Private Sub TicketNo_Label_Click()
If Me.OrderBy = "TicketNo DESC" Then
    Me.OrderBy = "TicketNo"
Else
    Me.OrderBy = "TicketNo DESC"
End If
Me.OrderByOn = True
End Sub
