App Id for Facebook not being applied

Hi there,

I added this code:

// APP ID
add_filter( ‘og_array’, ‘add_og_facebook_data’ );
function add_og_facebook_data( $og ) {
$og[‘fb’] = array(
‘app_id’ => ‘xxxxxxx’, // i have add our app id here
);
return $og;
}

When I check here:
https://developers.facebook.com/tools/debug/?q=https%3A%2F%2Fwww.biodynamicbreath.com%2F

I get this message:

Missing Properties
The following required properties are missing: fb:app_id

Any idea what I am doing wrong?
