Import code from sidebar in pages

Hi,
I would like to create a page on my blog where to import a sequence of code from the sidebar. For example there is the code for the archive in the sidebar and I want to create a page where to be viewed the arhive of the blog, meaning when a new month is being added to the sidebar to be automatically added in the created page too. If I try to copy and paste the code in the HTML source window when I click update the code disappears.
