shortcodes do not work

Hi,

I visited the usmls.com site and I like the way it looks, but I tried it and it doesn’t work for me.

The short codes look wrong.

The search works,but not the short code from the search only the html code for the search is working.

http://brockton-realestate.com/brockton-homes/

The link above is the short code for the residential listing / search, not working.
