        If last.Length < 1 Then
            f_str = total.Substring(total.IndexOf(first))
        End If

        End If
        Try
            f_str = ((total.Substring(total.IndexOf(first), (total.IndexOf(last) - total.IndexOf(first)))).Replace(first, "")).Replace(last, "")
        Catch ArgumentOutOfRangeException As Exception
