Adding menu to static front page

Hi, I seem unable to add a menu to my website, that actually links to the sections that are shown underneath the static front page. Whenever I add a menu (either the Main one or one I create), the menu options link to NEW pages instead of the sections of the same name that I have created as part of the Static Front Page layout. Can you please help?? I chose this template as it is a one page parallax and I want the menu options at the top (or from the front page) to just link directly via some kind of scroll down effect, not go to a new page itself which doesn’t then still scroll up and down to the other menu options. Does that make sense?

The page I need help with: [log in to see the link]
