I would like to use the google calendar embed code to add a viewable Gcalendar to my form.

If I add the code directly to the HTML Layout section of the form, it will display as I want.

However, I would like to add it as a form field to allow the "Auto Generate Layout" feature to work. When I try to add the embed code in the free text HTML field, it only displays the code text. If I use the "insert code sample" feature and add the embed code there as HTML, the form generates an error that says "syntax error, unexpected token" in a yellow box at the bottom right of the screen.

I assume there is just a formatting issue, but cannot figure it out. Is what I am trying to do even possible?

FYI: The embed code I am trying to use is in the format that follows:
<iframe src="calendar.google.com/calendar/MYCALENDARINFO" style="border: 0" width="800" height="600" frameborder="0" scrolling="no"></iframe>
