Sidebar not Displaying on Mobile

Hi,
The problem is that the sidebar is not displaying on mobile devices. For example on the following link (this is a dynamically generated page of a real estate listing) when you open it on a desktop or laptop you will see there is a sidebar there. But when opened on mobile the sidebar is not there, I would image on mobile the sidebar would be moved to the bottom of the page as this is a responsive theme but the sidebar is not there at all. Any help would be greatly appreciated!
