        <table  style="margin-left:360px;margin-top:0px;margin-bottom:0px;">
            <tr>
                <td style="text-align:left;font-size:12px;"><b>Jusqu'au mois courant:</b></td>
                <td>
                   <input type="radio" id="radio_budget_cumulee_jusque_mois_courant" value="courant" name="radio_budget_cumulee" />
