Making my first advanced CSS styled functioning website

I’m currently working on my online portfolio, a website that I’m making on my own just so I can increase my potentials for getting asked for a job and then hired. I’m also making it so I can convince some investors to invest in an 7 minute, dialogue free, animated short film that I want to make over the summer. I’ve selected a neat looking CSS template, quite professional and modern looking, Flash free, which I gave credit to on the bottom of the page, and I’m trying to make it where the links reveal specific divs related to the link I just clicked. Unfortunately, I’ve tried so many different methods, and none of them seem to work. I’m working on this for my own free will, not because a college professor asked me to. Here’s the HTML and Javascript Code code:

May someone please help me in getting these links to work so I can further use other tutorials to style up the divs that end up getting revealed by the links?
