Thank you, that doesn't seem to be working, I also added the following (in blue) to the Admin/module.php
if (tep_not_null($action)) {
switch ($action) {
case 'save':
foreach ($_POST['configuration'] as $key => $value) {
tep_db_query("update " . TABLE_CONFIGURATION . " set configuration_value = '" . $value . "' where configuration_key = '" . $key . "'");
} if( is_array( $value ) ){
$value = implode( ", ", $value);
$value = preg_replace ("/, --none--/", "", $value);
}
tep_redirect(tep_href_link('modules.php', 'set=' . $set . '&module=' . $_GET['module']));
break;
case 'install':
case 'remove':
