iWeb and Javascript

O.k. so I successfully mad a website with which all the content loads into an iFrame on the main page. To do this I deleted the nav bars on the other pages that served as content for the iframe. This works great but unfortunately, if someone is referred to my site via Google, they are stuck on that page. Now I could just put nav bars on those pages and set the iFrame to start scrolling at 100px down, but thats not what I want. I want someone who comes to my site from Google to be directed to the home page with their selected content in the iFrame. I heard that this was possible via Javascript, but I don't know how to do it. To be clear, I DON'T KNOW ANY TYPE OF CODING EXCEPT FOR A LITTLE HTML. However, I am a goodlearner and I am very good at following directions. If you could post or e-mail me step-by-step instructions on how to do this, I'd be VERY greatful.
