it is _____still______ the same wrong code when I view source of your page.
the source of your page shows:
Dateformat: 'yyyy-mm-dd',
when it should be:
dateFormat: 'yy-mm-dd',
your upload is not making it to the server.
before posting back again, please double check the page source in the browser by going to View -> Page Source to make sure the changed code is making it to the server.
