 * Hey everyone,
 * I have set up the plugin and created 1 custom field. After testing it I received
   the admin auto reply from WordPress but nothing from Mailchimp and my list was
   not updated.
 * In Mailchimp under Account > Extras > API keys > API Calls, I get the following
   error:
 * User Agent: MailChimp.0.4.29/RenzoJohnson
    **Response: (250) List_MergeFieldRequired**
 * Thank you in advanced,
 * Chris
