Redirect Thank-You-Page

Hi,

i would like to redirect the thank you page. I´ve tried the following snippet in my function.php but nothing happend. What must be done to use the redirect snippet or how to alter it?

add_action( ‘woocommerce_thankyou’, ‘bbloomer_redirectcustom’);

function bbloomer_redirectcustom( $order_id ){
$order = wc_get_order( $order_id );
$url = ‘https://yoursite.com/custom-url’;
if ( ! $order->has_status( ‘failed’ ) ) {
wp_safe_redirect( $url );
exit;
}
}

Kind regards
