Newsletter Hello Chic Part 2

Hello, 
Thank you for your help previously! I am so close to being able to share my site with others! Yay! I have created the Mailchimp account and downloaded the plugin and got the API all set up. Yet when I am on the webpage the newsletter sign up will say that people have successfully registered but it is not connecting with my Mailchimp account. I have updated the HTML code and all. Please help. Thank you!
 
My website is bellsandjulesco.com
