                <td class="etichette">Email</td>
                <td><INPUT type="text" readonly="readonly" name="email" maxlength="50" size="40" value="<?php echo($contenutoForm[8]); ?>" id="f20"></td></tr>
                <!--script type="text/javascript">
                    var f20 = new LiveValidation('f20');
