Connecting Forms to MailChimp

I’ve followed all of the steps from the webflow tutorial video for integrating mailchimp forms to webflow forms. At the footer i have a form for signing up to our email list. however, whenever someone fills it out they get an error message. mailchimp suggested that it was because webflow changes the code - even if you input the task action code form mailchimp into webflow properly.

Any suggestions?

Thanks so much!
