Google Calendar in Tab Not working

I am unable to get my google calendar to work in a tab. The code seems good outside the tab and is working properly.

When I look at the page errors I’m seeing “Refused to display ‘https://calendar.google.com/calendar/embed?height=400&wkst=1&bgcolor=ffffff&ctz=AmericaNew_York&src=cm9sbGluc2ZvcmQubmgudXNfNmpjanRlajBsZXJsNTBjbnFrMG8yZ2pqOTBAZ3JvdXAuY2FsZW5kYXIuZ29vZ2xlLmNvbQ&color=D50000&showTz=0&showCalendars=0&showTabs=1&showPrint=0&showTitle=0&mode=AGENDA’ in a frame because it set ‘X-Frame-Options’ to ‘SAMEORIGIN’.” but I am unsure how to fix this.

Thanks!
