 *
 * Send an email all users who have submitted Form A when Form B is submitted. This *should not* be used
 * to large numbers of notifications.
 *
 * # Instructions
 *
 * These instructions assume that Form A contains an Email field.
 *
 * 1. Add a Hidden field to Form B.
 * 2. Enable "Populate value dynamically" setting and configure settings (https://gwiz.io/2LgCdZS):
 *    - Type: Gravity Forms Entry
 *    - Form: Select Form A.
 *    - Value Templates / Value: Select Email field.
 * 3. Create a new notification.
 * 4. Set the Sent To / Send to Email value as the merge tag for the Hidden field we added in Step 1 (https://gwiz.io/2CfXccB).
 *
 * That's it. Populate Anything combined with this snippet will populate a comma-delimited list of emails in to the Hidden
 * field. This snippet will parse the comma-delimited list and send a separate copy of the notification to each email.

Fatal error: Cannot use object of type GPPA_Object_Type_GF_Entry as array in /public_html/wp-includes/class-wp-list-util.php on line 152

This isn't working when trying to populate values into a text field.

I have two entries on FORM A and only one email value shows in the on FORM B. I've update the function to match appropiate field IDs and added it to the site.

Additionally only one email is also sent even when I add the right merge tag in FORM B's Notification.

Using GF: 2.4.8.13 and Gravity Populate Anything: 1.0-beta-2.46

Any ideas?
