Google Calendar

My website http://go-sail.org/ has a calendar page that would display a google calendar.

It totally broke some how and I can’t figure out why it won’t work again. I have tried several of the plugins, but they are not working.

I have the following code on the page which I thought worked before, but its not displaying correctly.
