Hi,
To get it working you need an id, because of the way you have written your code. ( I show you at the end, what I think is a better way ) FROM: new Ajax.Updater('user_cert_type','inc/actions/certifications.php', { method: 'post', parameters:'agency=' + $(id).getValue()}); return false; TO: id ='user_cert_agency';new Ajax.Updater('user_cert_type','inc/actions/ certifications.php', { method: 'post', parameters:'agency=' + $ (id).getValue()}); return false; I have tested it on my local server and it works. ( firefox + ie7 ) Before </body> insert I would suggest you take away doing the onchange and use. <script type="text/javascript"> //<![CDATA[ $("user_cert_agency").observe('change',function(event){ Event.stop(event); id = 'user_cert_agency'; new Ajax.Updater('user_cert_type','inc/actions/certifications.php', { method: 'post', parameters:'agency=' + $(id).getValue()}); return false; }); //]]> </script> As it makes things clearer. Also it allows you not to have to worry about ' and " ( single quotes / quotes incase they get removed from my post ) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
