A couple of the most obvious structural issues I see are no starting <html> or <head>. Add in... <html xmlns="http://www.w3.org/1999/xhtml"> <head> Then your <title> and style info. You also have two <title> tag sets, you can only have one. You have a map and area coordinates in by your style info, that should not be in the <head> of the page and needs to be moved to the body. Also your <area> tags need to be closed with /> not the > HTML element names and ids cannot start with a number, so any that you have that start out with a number need to be changed. You also have a couple instances where you see a name in the attributes, but no id. Your doctype wants both (they need to be the same as well). Anytime you have something like <map name="11_1x1"> add in an id like this <map name="11_1x1" id="11_1x1"> There are then a bunch of target attributes written as target=main in your links that need to be target="main" (with quotes) as long as you have something named "main" that is being targeted. If you are just trying to keep the links from going to another page, <a href="#"> is enough. All of your <br> tags need to be changed to <br /> (watch caps here, all html tags in your chosen doctype need to be lower case) The "circle-c" for copyright needs to be changed to © in the source Special characters in file names should be avoided. You should only ever use letters, numbers and underscores or hypens. I see a lot of () in the names of your images. It "shoulnd't" be a problem, but it's best practice to stick to alpha-numeric with - and _ instead of spaces. That should give you a good start. Once those are taken care of, run the validator again and the remaining issues should be relatively straight forward to repair.
