code.jquery.com isn't a CDN, or is it? I wouldn't link directly there. No, there's no way to have a script tag fall back to a different file if one can't be reached. If you want to be sure of availability, host your own copy of the .js file. Or, use the copy that Google provides here: http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js For more information: http://code.google.com/apis/ajaxlibs/ -Mike
