Add New Social Profiles

Having issues with this as well and cant piece together what I did wrong. I followed the guide here:http://kriesi.at/documentation/enfold/custom-social-icons/

Downloaded and imported the yelp icon from fontello. I see it in tools like Icon List but can not get a new category in social profiles to show up.

// Register new icon as a theme icon
function avia_add_custom_icon($icons) {
$icons[‘yelp’] = array( ‘font’ =>’fontello’, ‘icon’ => ‘uf1e9’);
return $icons;
}
add_filter(‘avf_default_icons’,’avia_add_custom_icon’, 10, 1);

// Add new icon as an option for social icons
function avia_add_custom_social_icon($icons) {
$icons[‘Yelp’] = ‘yelp’;
return $icons;
}
add_filter(‘avf_social_icons_options’,’avia_add_custom_social_icon’, 10, 1);
