Floating Footer

Hi Folks;

I’m using the THATgolfTheme template and the footer locates at the bottom of the lowest text or picture on each page. I don’t know how to keep it at the bottom of the page. My site is located at http://bottsgroup.com/yes. I did try another of the provided templates and the problem did not occur using them. I’m not the most savvy person at this, but I’ve had a friend helping me in his spare time and he hasn’t been able to figure this out. Maybe someone out there can help me? The site was fine until 3 days ago when my friend came to work on it with me.
Thanks
