Add small editable box

Hi,

So far I have added text in a large section of the website through

<?php the_content(‘<p class=”serif”>Read the rest of this page »</p>’); ?>

being inserted btween the main page div, this being a big area.

I now have to add a staff profile page within this area on a new page and will include a photo of the staff member and a small amount of info about themselves, which my client needs to be able to adit.

The div that I need to contain this staff profile will only be 200px wide and be able to stretch.

Can anyone tell me what PHP I should be putting in to be able to add profile text and so the client can edit it.

Cheers
Geoff
