HTML and Photoshop

I have a problem with some of the HTML stuff while using Photoshop. please go to this page
i used Slices to make this thing. now if you click on INFO, it'll open up a site. but thats not what i want. what i really want is, if someone clicks on INFO, it should display the text in the big grey box on its right side, without opening any new window or anything, just within that box. in other words, how can i make that big grey box into a text area or something where i can write up HTML. for a working example, please visit Gorman's page

any sort of help would be highly appreciated. thanks.

have you thought about inserting the html for frames and using a coloured canvas as one of the frames?

You'll have to know a little bit about editing html but what the page you linked to is doing is:

Making a <.div.> inside a table and setting the overflow to scroll.

In order to make it appear when something is clicked you'll have to use the show/hide layers function.

I'm going to move this post to the code section since it isn't really a photoshop question.
