Radio Buttons

Hi: Can any one please tell me how to i create group of three radio button with following options

1. IMPORT PAYMENT process
2. CLOSE AND RETURN process
3. DEMOGRAPHIC AND RECON

On the first option it ask first the name of two input files

Private Sub selectfiles()
Dim MyFile As String
With CommonDialog1
    .DialogTitle = "Select First File"
    .ShowOpen
    TextBox1.Text = .FileName
    .FileName = ""
    .DialogTitle = "Select Second File"
    .ShowOpen
    TextBox2.Text = .FileName
End With
End Sub

Thanks.
