All posts link to the same one, differant urls

Need a little help please. Just launched my 3rd blog, copied a theme from my other one that works fine. But in this new blog no matter which article I click on the same content comes up. The site has 3 posts, and all three posts are on the homepage, and no matter which post you click on in the nav all three posts appear in the same order. The only thing that changes is the url. The url does look like it changes to the new page.
