Motorola Droid 2 :: Can't Create Calendar Entry

I can't create a new entry in Calendar. When I long-click on a time and select New Event, it says "You must synchonize a calendar before creating a new event."

OK, so I try syncing to my Google account. But when I go into Settings in my Google account (Settings, Accounts, Google) I only see Sync Contacts and Sync Gmail. (Gmail syncing works fine.) I don't see Sync Calendars.

Furthermore when I go into the Calendar app on the Droid 2 and select More, Calendars, no calendars show up.

So I think there's something missing. I don't see a way to add the calendar to my Google account on the Droid 2.
