Error with embedded code in Adobe Portfolio

[#1]

Hello, 

I try to use embedded code in Adobe Portfolio. I want to embedded a button to sign up for a newsletter. I would like to maintaine that through mailchimp. Mailchimp provides preconfigured code to copy paste to websites. I used the same code with another Webdesigner tool without problem but in Adobe Portfolio I get the message that the code is not correct - but nothing else. 

Is there a way to undertsand why the preconfigured code is not working - I have not so good html skills to verify myself. 

Thanks for any hints.

If your embed code is not inside an <iframe> it won't work in Portfolio, sorry.  Portfolio does NOT accept embedding via URL or HTML.  See below for details on the Embed Module in Portfolio.
