Adsense On Blogger.com

How do I paste the AdSense code in the box unit blogger.com html?
I copied and pasted without any modification (I do not even know not how). But his story to me Your model could not be parsed as it is not well formed. Please make sure that all XML elements are closed properly. XML error message: The markup in the document following the root element must be well trained. This is nd its exact message me. Have you ever had this message and what it means?
XML requires a single tag that normally do not need to be closed in HTML 4.01 to be closed. You add a space and a "/" character at the end of the closing tag for: like alt = "Description" text /> This tag includes the break, meta tags and links, etc.. Ron
