Fix search function on my site

I have the website [login to view URL] On each page, there's a Google search bar on the top. I've somehow messed something up, and when a visitor types in a search, they get the results, but the results are BEHIND the text and images. I want the results to show up on the same page (which it does), the top header to be there (which it does), and I want the left-side menu to be there (which it does), but I don't want the old text and images to show up, I want just the results to show up. Can you help? Please only bid if you fully understand the directions. I'm hoping that there is an easy fix.
