iframe codes don’t work in Sermon Details

I am building a website for my church, and I’ve been trying to get an iframe embed of our church’s soundcloud upload but whenever i copy and paste the iframe code provided by soundcloud into the “Description” section in the Sermon Details, it never saves.

If I use a simple embed code, not much of a problem… but I kind of need to use the iframe embed to adjust for design later.

Does the plugin simply not allow iframe embed in the description section? if not would it be possible to allow it?

The page I need help with: [log in to see the link]
