dont boader for the function
the problem is here -> "<option>" . '$content_' . $lang . "</option>"
there is the complete script:
$myregime=mysql_query("select * from $mysql_db_miscfield where useit='regime' order by id");
while(list($cid,$usemy,$code2,$content_fra,$content_eng,$content_deu,$content_lux)=mysql_fetch_array($myregime))
{
if ($regroom == $code2) { $selected=" selected"; } else { $selected=""; }
echo " <option value=\"$code2\"$selected>" . '$content_' . $lang . "</option>\n";
}
