php and <div> tag

[schkeb]

Hi.
I am making a site that has two columns using <div> tag, the one to the left is going to be the menu, and the other the main window.

I'm using the php 'include' command to load a menu.php on the left <div>, and a welcome page in the main <div>.

The object is now to get links from the menu to show in the main window.

From menu.php:

<a href="http://www.google.com" target="main">Google</a>

This should load google in the <div> main, but nothing happens.

How do I get the main <div> to include whatever gets called from a link from the menu?

[edit]rephrase: I'm trying to send a link from menu.php to the <div class="main"> which is defined in index.php[/edit]
