            Dim params() As SqlParameter = {New SqlParameter("@ClientID", Request.QueryString("ClientID"))}

            Dim myReader As SqlDataReader = Nothing
            myReader = SqlHelper.ExecuteReader(Connstring, CommandType.StoredProcedure, "IPA_cert_insert", params)
            If myReader.HasRows Then
