Trouble with Mail Chimp integration

Hi all,

I am trouble linking a MailChimp sign-up form to my website:

It appears that I have successfully mapped the form fields and I have included the correct Form Action link, but once I published the site, the submit button doesnt do anything.

I am stuck and dont know how to troubleshoot from here. Any insight would be much appreciated!
