One tinsy Issuee I'm havinggg Options

[Jamesisgsnap]

So a friend helped me with coding my website, and I thank him soo much for like, showing me a few things, etc.
Now, My issue is, I have a domain Layout, perfect aligned, everything(didn't add my Ads yet)
And I have everything up, But when Ever I add something, the adbars would move down, like they're BEHIND the Main Section. And so My friend tried something, and it worked.
But when I took out the Page graphics, they disappeared, meaning he aligned them so that when something the size of the 100 Page graphics that I added goes away, they go up; If you add something the same size, they perfect align.

Any Suggestions how to keep the sidebar Like, completely there?

Well, the reason why I have atleast 100 Warnings/errors is because the Page graphics on the practice page.
It says

The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.

Typical values for type are type="text/css" for <style> and type="text/javascript" for <script>.

It's also giving me errors On my Links?
Like, Not the <a href=""></a> but the url to it.
