integrating with GD Star Rating

Hello

I would like to render the review of my products when people share the content.

GD Star Rating plugin uses this function for rendering
wp_gdsr_render_review();
http://www.dev4press.com/document/function/wp_gdsr_render_review/

I have tried to use your suggestion below but it is not working. Any recommendation??

<?php
if ( function_exists( 'wpmudev_pwal' ) )
     echo wpmudev_pwal( custom_description() );
else
     echo custom_description();
?>
Also create a function in your functions.php to call necessary css and js files, like so:
<?php
function my_pwal_customization( ) {
     global $pwal;
     if ( !is_object( $pwal ) ) return;
     $pwal->load_scripts_styles();
}
add_action( 'template_redirect', 'my_pwal_customization', 2 );
?>

Thanks
