My fixed navbar doesn't work properly

Question

I made a fixed navbar, but when I scroll you see the navbar behind the other images. I don't know what I am doing wrong. Here is a link with the navbar (it supposed to fit in the white bar but in Dreamweaver it all looks good).

So I want the fixed navbar that scrolls over all the divs. Please help. Thanks

Could you use in your CSS the z-index property?

Like so:

z-index:999;
