Blog Masonry with side channel

Hi there

You show on your demo that you can have a masonry layout with a left or right side channel yet mine only shows the default single post layout.

Mine looks like this: http://www.actuationconsulting.com/new/product-management-blog/

Can you tell me how to get it to look like this?

Though actually i would like the side bar to be on the right.

thanks!
