Dim count As Integer

            count = CInt(ComboBox1.Text = "-- Please Select --")
            count += CInt(ComboBox2.Text = "-- Please Select --")
            count += CInt(ComboBox3.Text = "-- Please Select --")
            count += CInt(ComboBox4.Text = "-- Please Select --")

            If count <> -3 Then
                  MessageBox.Show("Bad")
            End If

I think you should look for some control alternative like this:
a combo box with a "tree-view" like display
