Widgets/Sidebar Showing at Bottom at Site, not on right hand side

Hi there,

I am using the twenty eleven theme and the widgets/sidebar are appearing at the very bottom by the footer, rather than along the right hand side. What part of the code is wrong/do I need to change? I have tried changing recent posts to drafts (the ones I posted after the change occurred) and then updating and that didn’t work. Any suggestions? I am realizing more and more that coding is not for me- any recommendations on designers who aren’t expensive?

Thank you!!!
