iCal + Google Calendar help

I read the thing where you can sync the Google Calendar and iCal with CalDAV. I did what was in the instructions on Google where I enter my username password and this link in the server options. https://www.google.com/calendar/dav/YOUREMAIL@DOMAIN.COM/user

Whenever I click add though it says that no calendars could be found. Is there something I'm missing? Yes, I have a Google calendar and yes I replaced the thing in the URL.

Any help is appreciated.

 

Sweet, thanks man it worked!
