[Plugin: bbPress] How to make display WordPress Roles in bbPress Replies?

Hello support.
I will launch my site soon and i need to achieve this,for example my members will register to my site through s2member plugin which created Copper Member (Level 1),Silver Member (Level 2) and Gold Member (Level 3) and i will need to see in Forums what role they have when they ask a question for support.
I have searched for a solution and found this
Topic i have put this code as he explained but not worked.

bbp_reply_author_link( array( ‘sep’ => ‘<br />’, ‘show_role’ => false ) );
$reply_author_id = get_post_field( ‘post_author’, bbp_get_reply_id() );
$user = new WP_User( $reply_author_id ); if ( !empty( $user->roles ) && is_array( $user->roles ) )
{
foreach ( $user->roles as $role )
{
/*if (preg_match(“/”.$roles.”/i”, “administrator”))
{
echo(“Administrator”);
break;
}
else*/
echo “<div class=’role_custom_bhush’>”.ucfirst($role).”</div>”;
break;
}
}

Maybe i do something wrong, can someone help please?
