Trying to get custom js files in my admin header

Ahh ok I figured it out while researching. I needed to add the $hook parameter and pass it to my function like so:

function my_admin_enqueue_scripts($hook) {
    global $current_screen;

    if ( 'post.php' != $hook )
        return;
    wp_register_script('my-scripts', get_template_directory_uri() . '/js/custom/my-scripts.js' );
    wp_enqueue_script('my-scripts');
    wp_localize_script('my-scripts', 'wp_ajax', array( 'ajaxurl' => admin_url( 'admin-ajax.php' )));
}

This gave me the results I was looking for. Thank you!
