Paging of 2 tabs using 1 control variable for page numbering

Next, I have a page that has 2 tabs and in each tab there is pagination, the problem is that I need to use the variable "$ pagina " for both tabs as a way to control the page number without changing both the tabs, how would?

Below my code

.cinza{ background: #c8c4c4; height: 22px; color: black; } } 
.claro{ background:#f9f9f9; height:22px; } 
.fonte{ color:white; font-weight:bold; height:25px; }



       <?php
          // conexão com o banco de dados 
            @mysql_connect("localhost","admin","123456"); 
            @mysql_select_db("db_mining");
            $max = 100;
            @$pagina = $_GET['pagina'];



                @$divisao     = $_POST['divisao'];@$_SESSION['divisao'] = $divisao;
                @$demandante  = $_POST['demandante'];@$_SESSION['demandante'] = $demandante;
                @$num_demanda  = $_POST['num_demanda'];@$_SESSION['num_demanda'] = $num_demanda;
                @$assunto     = $_POST['assunto'];@$_SESSION['assunto'] = $assunto;
                @$data_registro = $_POST['data_registro'];@$_SESSION['data_registro'] = $data_registro;




                            //_SESSION['SQL'] = $_SESSION['RETURN'];

                        //if (empty ($busca) or strlen ($busca)< 2 )
                        //{
                        //    echo "<script> alert ('Digite um parâmetro com pelo menos 2 caracteres!') </script>";
                        //    echo "<script> location.href = ('form_busca.php') </script>";
                        //    exit ();
                        //}
