Um using dreamweaver I added an adsense code to the right sidebar. For some reason it has moved the sidebar to the left along with the body and it has messed up the right sidebar. Anyone have any idea what has happened?

You don't have any CSS code for your left sidebar and your right sidebar should be;

.sidebar2 {
background-color:#FFFFFF;
float:right;
padding:10px 0;
width:195px;


}

and as an aside your header/logo should be a gif or 8-bit png

Does anyone know how to make to make the content section appear in the middle?

What he said is the answer.
So try following that.

First of all, you have a number of things wrong in your code;

<style type="text/css">
<!--

You cannot use html-style comments inside the <style> tags, you have to use /* xxx */ to comment out code.

Secondly, you have this error in your css:

background-color: #FFF;
}

That bit of css is just hanging in the middle and is not properly formatted nor applied to anything.

You also have javascript stuck inside the <style></style> tags, that won't work either, it cannot be there.

Once you fix these errors, you'll see improvements in your page.

I apologize if I am incorrect as I'm slightly new to setting up css but isn't the left sidebar have the css

.sidebar1 {
float: left;
width: 195px;
padding-bottom: 10px;

your header/logo should be a gif or 8-bit png

Why? There's no reason not to use a transparent 24-bit PNG or even a jpg if it fits.

No, you didn't, not completely - and there's no reason he couldn't have floated it left also, it would have worked just as well.

Why do you have position: fixed on your .content div? Get rid of it and your center column will go where you want it.

You also have not removed the improper comments or the script in the middle of your css.
