Hello again :)
target is a deprecated attribute that only ever worked with frames and iframes...
if you want to load information into a DIV, then you are going to have to look into Ajax
I recommend that you get the prototype scripts from http://www.prototypejs.org/ and include that into your page... then you can use their Ajax classes to change the content of a DIV...
the simplest thing would be to have a file with a block of HTML, and use onclick events to trigger an Ajax update:
<script type="text/javascript" src="protoype.js"></script>
<script type="text/javascript">
function change_content(elementname, filename)
{
new Ajax.Updater(elementname, filename);
}
</script>
<div id="not_a_frame">
</div>
<a href="" onclick="change_content('not_a_frame', 'some_content.html')">content 1</a>
<a href="" onclick="change_content('not_a_frame', 'other_content.html')">content 2</a>
As far as I'm aware - the filename can take any path relative to the current pages location on the server...
Also, links which are included inside the <div> will also work - even after the content has changed, as long as they reference the correct ID attribute
Finally, you do not need (actually, you do not want) these "included" files to be full HTML documents (so no <head> or <body> - just the section of content to go between the <div> tags).
