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.
