How to pull video code from CMS collection to HTML embed field

Hi there. I’m trying to add a HTML video to our projects page using HTML embed and video code from CMS collection. The code works fine when its pasted directly to the HTML embed element, but then it would be on all of our projects. Not what we want. When I add the video code field to HTML embed element it shows the code (writen in letters) in our project.
How can I make HTML embed element play the video? All help very much appreciated :pray:
