Site breaking after adding php

Hello, I am trying to add a video slider above the featured pages on the homepage.
I have my child theme setup and I am adding this code:
add_filter( ‘tc_default_widgets’ , ‘add_featured_page_widget’ );
function add_featured_page_widget( $defaults ) {
$defaults[‘fp_widgets’] = array(
‘name’ => __( ‘Featured Pages Widget’ , ‘customizr’ ),
‘description’ => __( ‘Above the featured pages area on home’ , ‘customizr’ )
);
return $defaults;
}

add_action(‘__before_fp’ , ‘display_my_fp_widget’);
function display_my_fp_widget() {
dynamic_sidebar(‘fp_widgets’);
}

from https://themesandco.com/snippet/adding-widget-area-home/

Regardless of what I do, it always breaks my site and I end up having to re-install the theme. Note sure what I am doing wrong. Is there an easier way to add a video slider?

Thanks in advance!
