Invalid Embed Code
I am creating an Engage interaction and I would like to insert a video from a website. I followed the instructions and copied the embed code from this youtube video: http://www.youtube.com/watch?v=CPEoEcs2oLs&feature=youtu.be
So I entered this as the embed code (straight from youtube site):
<iframe width="560" height="315" src="//www.youtube.com/embed/CPEoEcs2oLs?rel=0" frameborder="0" allowfullscreen></iframe>
It says that it is an invalid embed code. What am I doing wrong?
