Access 2010 hide form/switchboard after open form selected

On my Home page (Switchboard) "On Open" event I would like to close the form after the selection is made for R100, S100 or M100.

Here is current code:

Option Compare Database
Option Explicit

Private Sub Form_Open(Cancel As Integer)
If Forms("frmLogin").txUserLevel = 1 Then
  Me.R100.Enabled = False
  Me.S100.Enabled = False
  Me.M100.Enabled = True
ElseIf Forms("frmLogin").txUserLevel = 2 Then
  Me.R100.Enabled = False
  Me.S100.Enabled = True
  Me.M100.Enabled = False
ElseIf Forms("frmLogin").txUserLevel = 3 Then
  Me.R100.Enabled = True
  Me.S100.Enabled = False
  Me.M100.Enabled = False
ElseIf Forms("frmLogin").txUserLevel = 6 Then
  Me.R100.Enabled = True
  Me.S100.Enabled = True
  Me.M100.Enabled = False
End If
End Sub
