[LISTINGS] by distance?

I’m using the following shortcode on my homepage:
<?php echo do_shortcode(“[LISTINGS orderby=’distance’ show=’3′ grid=’yes’]”); ?>

but Its not ordering by distance… also how would I only shower ‘featured’ listings by distance? I tried adding features=”yes/1″ but could not get that to work either.

Thanks!

P.S.: I would not have to keep making forum posts if documentation was available.
