No comments or content in the side bar

Todays problem to fix is the absence of comments. I have signed up to Haloscan to manage all the comments but the HTML for the blog page does not seem to include a link to Haloscan to offer the ability to leave a comment. I think that I have ticked the right boxes within the setup area of the editing section in Rapidweaver but no joy. I will investigate later. I am also lacking content in the sidebar such as an archive and category list. Let's see what can be done...
