PHP error for Ipdiscover : PHP Fatal error: Call to undefined function formGroup()

Hi,

I'm trying to perform an IPDiscovery using a Linux agent for my Windows OCS Server, but when I try to access the IPdiscover table, I only find a blank page.

Here is what I find in my httpd error_log :

PHP Fatal error:  Call to undefined function formGroup() in /usr/share/ocsinventory-reports/ocsreports/plugins/main_sections/ms_ipdiscover/ms_ipdiscover.php on line 63, referer: http://10.132.13.48/ocsreports/index.php?function=debug&head=1

So i checked the file and here si the part of the code where the error is :

if (isset($_SESSION['OCS']["ipdiscover"])) {
    $dpt = array_keys($_SESSION['OCS']["ipdiscover"]);
    array_unshift($dpt, "");
    foreach ($dpt as $key => $value) {
        $list_index[$key] = $value;
    }
    asort($list_index);
    $list_index[0] = ' ';
    ?>
    <div class="row">
        <div class="col-md-8 col-md-offset-2">
            <?php formGroup('select', 'DPT_CHOISE', $l->g(562), '', '', $protectedPost['DPT_CHOISE'], '', $list_index, $list_index, 'onchange="document.ipdiscover.submit();"'); ?>
        </div>
    </div>

    <?php
} else {
    msg_info(mb_strtoupper($l->g(1134)));
}

Any help?

Thx
