Blog posts missing

Hi
I have a basic website with 5 pages, 4 static(template pages) and a blog page for all dynamic content. The templates used for the blog page include the header.php, sidebar.php, the index.php, and footer.php. The sidebar.php(right col) shows all the info and the links work as expected, but the blog page fails to show post/posts in the main left column when opening the blog page for the first time. website here<a href=”http://www.smpwebco.com

Thanks for any help
