What's wrong with my PDO syntax? Is it possible to get a clearer error report?
$dbh = new PDO("mysql:host=" . WEBSITE_SERVER . "; dbname=fluenz_website", WEBSITE_LOGIN,   WEBSITE_PW);
$query = $dbh->prepare("INSERT INTO crm_orders (crm_id, order_num, channel) VALUES (:crm_id, :order_num, :channel)");

if($query->execute(array(':crm_id'=>$crm_id, ':order_num'=>$order_num, ':channel'=>$channel))){
    echo 'PDO SUCCESS';
}else{
    echo 'PDO FAILURE';
}

$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

try {
    $query->execute(...);
} catch (PDOException $e) {
    echo $e->getMessage();
}

try {
    $dbh = new PDO($dsn, $user, $password);
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
    echo 'Connection failed: ' . $e->getMessage();
}

try {
  $query = $dbh->prepare("INSERT INTO crm_orders (crm_id, order_num, channel) VALUES (:crm_id, :order_num, :channel)");
