Activity Stream Filter

I need to filter the main activity stream to just people the user is following, and themselves.

I have tried this: <?php if ( bp_has_activities( bp_ajax_querystring( ‘activity’ ).’&scope=following&action=activity_update’ ) ) : ?>

But had no luck, I am a bit at a loss where to start.

Thanks,
