Disabling first row of listbox

Greetings,
I am using the following code to access an Userform listbox. I am needing to disable the first row from being accessed.

Private Sub ListBox1_DblClick(ByVal Cancel As MSForms.ReturnBoolean)
Dim c As Control

If IsNull(Me.ListBox1.Value) Then
    tName.SetFocus
Exit Sub

Else
REP_SetUp_2.tName = REP_SetUp.ListBox1.List(REP_SetUp.ListBox1.ListIndex, 0)
REP_SetUp_2.tCell = REP_SetUp.ListBox1.List(REP_SetUp.ListBox1.ListIndex, 1)
REP_SetUp_2.tEmail = REP_SetUp.ListBox1.List(REP_SetUp.ListBox1.ListIndex, 2)

For Each c In Me.Controls
    If TypeName(c) = "TextBox" Then '''
    c.Value = ""
    End If
Next c
End If
Unload Me
    REP_SetUp_2.Show
End Sub
