Layout Troubles...

I'm not the most technologically savvy person out there, but I am having troubles with my Blogger layout and can not for the life of me figure it out. The blog archives and my sidebar pictures have been moved to the bottom of the blog for some reason. I've even deleted everything and started from scratch and it isn't fixing the problem. If anyone can think what I might be doing wrong, please let me know! Otherwise, until further notice, the archived posts are available at the bottom of the page. Thanks!
