Just put in the selectedindex change event of the first combo box, something like:

If cb2.SelectedIndex = -1 Then
            MsgBox("You must select a country.", MsgBoxStyle.Information)
            Exit Sub
        End If

sorry i dont get what u mean by Just put in the selectedindex change event of the first combo box.

Just select the SelectIndexChanged event of the first combo box...

Private Sub cb1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cb1.SelectedIndexChanged
      If cb2.SelectedIndex = -1 Then
                  MsgBox("You must select a country.", MsgBoxStyle.Information)
                  Exit Sub
              End If 
    End Sub

I'm assuming that your combos are called cb1 and cb2, so you probably need to change the names...

You need to change test value... Don't use -1 becuase -1 indicates nothing is selected by the user. Change -1 to whatever index that "Unlisted" is on in your list. Remember, index in a collection is zero based, so if Unlisted is the 2nd item in the list, its index is 1.
