Embed Calendar on website and in phone app?

Embeding calendar on website.
I follow the direction to get the link to embed on my website.  I "enabled" online appointments.  I entered the code under "raw HTML" on website and it doesn't bring the calendar in. 

ALSO 
I have an phone app that I created.  How do I get a code that will embed within my appy phone software.  (There is not a website address I can type in Charm to get a link for the calendar.


Any suggestions?
