Please set a message!

Don't know what to do to correct "Please set a message!" error message and to get the footer subscription form to submit correctly.

Thank you for any help.

Here is include/subscribe.php Seems tied to MailChimp ... which I do not use. I could drop this into CampaignMonitor which I do use. Thank you.

<?php

$apiKey = ''; // Your MailChimp API Key
$listId = ''; // Your MailChimp List ID

if( isset( $_GET['list'] ) AND $_GET['list'] != '' ) {
$listId = $_GET['list'];
}

$email = $_POST['widget-subscribe-form-email'];
$fname = isset( $_POST['widget-subscribe-form-fname'] ) ? $_POST['widget-subscribe-form-fname'] : '';
$lname = isset( $_POST['widget-subscribe-form-lname'] ) ? $_POST['widget-subscribe-form-lname'] : '';
$datacenter = explode( '-', $apiKey );
$submit_url = "https://" . $datacenter[1] . ".api.mailchimp.com/3.0/lists/" . $listId . "/members/" ;

if( isset( $email ) AND $email != '' ) {

$merge_vars = array();
if( $fname != '' ) { $merge_vars['FNAME'] = $fname; }
if( $lname != '' ) { $merge_vars['LNAME'] = $lname; }

$data = array(
	'email_address' => $email,
	'status' => 'subscribed'
);

if( !empty( $merge_vars ) ) { $data['merge_fields'] = $merge_vars; }

$payload = json_encode($data);

$auth = base64_encode( 'user:' . $apiKey );

$header   = array();
$header[] = 'Content-type: application/json; charset=utf-8';
$header[] = 'Authorization: Basic ' . $auth;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $submit_url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);

$result = curl_exec($ch);
curl_close($ch);
$data = json_decode($result);

if ( isset( $data->status ) AND $data->status == 'subscribed' ){
	echo '{ "alert": "success", "message": "You have been **successfully** subscribed to our email list." }';
} else {
	echo '{ "alert": "error", "message": "' . $data->title . '" }';
}

}

?>

Nevermind.

I finally figured it out.

I needed to take the Campaign Monitor php, complete it, and upload it as subscribe.php

We are in business.

Thank you.
