Hi again, is the content in the sidebar underneat the slider on the left inside a 'content sidebar'?
If so you'll need to move the widgets from inside the content sidebar in to one of the main sidebars (sidebar primary,secondary etc) these are the main full height sidebars which span the full height of the site. The content sidebar will only span the height of the content area.
So remove the content sidebar widgets into one of the others (probably secondary as it looks like primary is on the right already) then remove the content sidebar from the content area. Then select in the layout edit one of the two sidebar layout options - http://screencast.com/t/7ucDOXcDfpaGo to the full post
