I have included my Google calendar that I set up for my classes to post assignments (in agenda view). You should click on the pencil above to edit this page. Delete my entire Google calendar gadget (the big grey box). Then click on Insert in the menus in the upper-left corner. There should be an option for a calendar in the 3rd column. When you add the calendar, you will have an option to choose from the Google calendars associated with your account.
