Hello, I'm trying to populate a dropdown box in a RSForm using this code: //<code> $db = JFactory::getDbo(); $db->setQuery("SELECT Bruel_ID FROM mpctz_rsform_bruels"); return $db->loadObjectList(); //</code> However, it displays nothing in the box and some code outside of it (see attached file). Can anyone help? Thanks, Dani
