# Invalid argument error message

 * Glad to see an update for this plugin! It looks like the changelog is missing
   some info though?
 * I am using WordPress 4.1, Gravity Forms 1.9.beta3, and the Constant Contact Add-
   On 2.2.1. I tested a simple mailing list subscription form with just an email
   address field that is linked up to a Constant Contact account.
 * This test seemed to work fine, the email addresses I entered showed in the proper
   contact list in Constant Contact. But there is an error that pops up when the
   confirmation message loads using AJAX:
 *     ```
       Warning: Invalid argument supplied for foreach() in /nfs/c01/h01/mnt/1111/domains/domain.com/html/wp-content/plugins/gravityforms/includes/fields/class-gf-field.php on line 16
       ```
   
 * Should the latest update have resolved this error, or is this a new or different
   issue?
