Hi!
I have a problem with a small effect.
The idea is to dynamicly change the pages in a single box, and the header and the footer of the main page to hide or show the box with the information.

That's the idea..

<?php
session_start();
	require "config.php";
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
	<head>
    	<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
		<title></title>
        <link rel="stylesheet" href="css/main.css" type="text/css" />
        <script src="javascript/jquery-1.5.1.js"></script>
	</head>
	
	<body>


	<div class="manga_header"></div>


    <div id="header">
    	<div style="background-image:url(body/header/bg.png); width:880px; height:290px; position:relative; left: 17%;">
    		<img src="body/header/mermaid.gif" width="232px" height="232px" align="center" style="position:relative; left:34%;" />
                <div class="left_m">
                    <a href="index.php?page=home" class="lol"><img src="menu/home.png" style="margin-top:10px; margin-left: 10px;" width="100px" height="50px" border="none" /></a><br />

                </div>
                
                <div class="right_m">
                	<a href="index.php?page=gallery" class="lol"><img src="menu/gallery.png" style="margin-top:10px; margin-left: -15px;" width="100px" height="50px" border="none" /></a><br />
                    <a href="index.php?page=works" class="lol"><img src="menu/works.png" width="100px" height="50px" border="none"/></a><br />
                    <a href="index.php?page=porychai" class="lol"><img src="menu/porychai.png" width="100px" height="50px" border="none" /></a><br />
                    <a href="index.php?page=join" class="lol"><img src="menu/join.png" style="margin-top:-5px; margin-left: -15px;" width="100px" height="50px" border="none" /></a><br />
                </div>
                
        </div>
    </div>

    <hr />
        <div id="drop_down">
			<?php
            $page = (isset($_GET['page'])) ? $_GET['page'] : 0; // identifies the variable
            
                switch($page){
                    case "home":
                    include "home.php"; break;
                    
                    case "next":
                    include "next.php"; break;
                    
                    case "news":
                    include "news.php"; break;
                    
                    case "register":
                    include "register.php"; break;
                    
                    case "more_info":
                    include "more_info.php"; break;
                    
	            case "join":
                    include "join.php"; break;
					
		    case "gallery":
		    include "gallery.php"; break;
					
	            case "works":
		    include "works.php"; break;
					
		    case "porychai":
		    include "porychai.php"; break;
					
                    default:
                    include "home.php"; break;
                }
				
            
            ?>
        </div>
    <hr />
    <div id="footer">
    	<div class="friends">
       
        </div>
    </div>
	</body>
</html>
  <script>
			$(document).ready(function() {
				
						$(".lol").click(function(){
												
							if($("#drop_down").is(":hidden")){
								$("#drop_down").slideDown("slow");
								return false;
							}
						})
				});
	</script>

I want to click on a link and then the slide effect to be shown, and after that the information from the current page that is called from the link.

(Sorry for the bad english..)
