On lottorevenues.com home page, clicking the "contact" link in the menu takes me to the page contact.html, which is what I would expect. The other links in that menu are internal page links and therefore take me to other parts of the home page - also what I would expect. So in what way do you mean it's not working for you?
I suspect your problem lies with your JS, which is not my forte. Either way, you need to work out why your styling is only being applied when JS is enabled - that's definitely not right. :)
