I made sure though that before I started altering the HTML that I made a backup of the Blogger template... just in case.
I was very pleased when I finally clicked on save to see it had worked, although I still have to alter the column sizes and our logo size as it now looks to narrow at the top of the blog.
After much research I found that this website helped with the codeing.
