PaulHaydock1982 on "Next / Previous links updating div content"

Hiya,

I'm trying to modify my current theme and I've run into an area thats got me stumped.

http://paulhaydock.com/

In my main blog box, I'm using the following code:

<!--POST SECTION-->
<div class="eslabout">
    <ul class="idTabs">
        <li>
            <a href="#news">
                Blog
            </a>
        </li>
    </ul>
    <div style="clear: both;"></div>
    <div id="news">
        <div class="subabout"  style="min-height: 485px">

Followed by the post etc...

What I want to do is create Previous and Next post buttons in the list were currently I have the word 'Blog'...and to load the content into the div without having to reload the page for the posts.

Anyone able to help / advise?

Thank you in advance,

Paul
