Need help with jQuery nav bar

Need help with jQuery nav bar

Hey all. This is my first post here, so I'm sorry if it's in the wrong place.

What's going on?: I have a navigation bar implemented on my page using this tutorial.
http://blog.themeforest.net/tutorials/jquery-for-absolute-beginners-day-7/
      I then added links to each of the images/buttons to direct you to other places on the page, and used CSS to position it.
      Once everything was complete I put every thing in the page (including the the jQuery included in the body) in a container using a <div> tag. I know I should have put it in the container to begin with, but, I'm a student. Unfortunately.
      Now once I put page was in the container, my navigation bar isn't working. And just to note it was working exactly how I intended it to before it was placed in the container. I took the navigation bar out of the container but it won't work unless I remove it's CSS properties all together. I asked my professor and he doesn't seem to know what the problem is or he's just to busy to help me. So, if anyone could lend a hand it would be greatly appreciated, my applied portfolio needs to be done by the end of the week. Thanks!
