I fixed 12 errors and now have 3 which I have no idea on how to fix. Please point me in the right direction or please explain to me how to fix these errors or what they mean.

get rid of the non-existent height attribute and the background attribute in line 42.

And the warning is because you have used a XHTML self closing element /> with a HTML 4.01 doctype.

-------
Line 19, Column 29: required attribute "TYPE" not specified.
<script language="JavaScript">
-- correct: <script language="javascript" type="text/javascript">
-------
Line 51, Column 18: there is no attribute "MARGINWIDTH".
<body marginwidth="0" marginheight="0" bgcolor="#ffffff" leftmargin="0"
-- like it says, there is no valid marginwidth, LEFTMARGIN, etc... you can make it from CSS: body {margin:0}
-------
Line 52, Column 128: there is no attribute "BACKGROUND".
…ign="top"><td width="50%" background="images/bg.gif"><img width="1" height="1
-- you must have <td class="my_bg" and CSS: .my_bg { background-image:url(images/bg.gif)}
-------
you must learn some CSS

8 errors now I can see of.

While it's a good way to learn standards everytime to validate your markup, it's rarely useful for site performance.

Standards compliance can help alot with SEO. If the spider can't figure out what's on your site, it isn't going to index it....

It's also useful for ensuring that your site looks right in all of the different browser possibilities that your site will encounter. It's always easy to start with standards compliant code, before you begin testing between different browsers.

but why are saying this?

Often if one of my sites does something funny that there doesn't seem to be an obvious first solution to, I will immediately validate to see if I made a simple error. Validation is great for catching unclosed list items, unclosed tags, simple syntax errors such as dropped semi-colons in CSS files, etc. Validation is not the be-all end-all, although it is certainly meaningful. Most of my CSS files don't validate because I use the underscore hack to target IE6. Needless to say, this does not affect site performance in the least.

try putting them in your CSS

i created a div and put all this in the CSS and it passed validation

{position:relative;height:900px;background-color:#000000;width:140px;border-right: 3px solid white; float:left}
