API Google Maps Error Still I followed your instructions

Hi I followed your instructions to a T and I am still getting the errors.

Here is my code from the framework/inc/shortcodes.php

——-*/
function minti_load_googlemaps() {
wp_register_script( ‘google-maps-api’, ‘//maps.google.com/maps/api/js?key=AIzaSyAZef_ta8axKhCWdbpCgCQhrFd7pu4tzzE’, false, NULL, true);
}
add_action( ‘wp_enqueue_scripts’, ‘minti_load_googlemaps’ );
