Error Submitting Signup Form

Trying to get an email optin to work. Using shortcode. Have it in test mode.

When I submit the form I get the following message:

Something went wrong, please try again.

Here are the 2 errors from my console:

Uncaught ReferenceError: group is not defined

Any ideas?
