Hello

im trying to create a settings page for a script im working on

i want to use a variable 'l' for the link of an iframe

ive written this

settings.php

<?
/*
THIS IS YOUR SETTINGS PAGE
USE THIS TO CONFIGURE THE ITEM SWITCHER
WE HOPE YOU ENJOY OUR PLUGIN
*/

// STEP 1: CHOOSE YOUR THEME : 'green' 'orange' 'blue' 'pink' 

$color = 'blue'; // change between the ' '

// STEP 2: CREATE YOUR MENU

/* HERE IS OUR PRE-DEFINED MENU SEE DOCUMENTATION TO ADDING MORE ITEMS */

$menu = '       <li class="is-nav-li">
                	<a href="http://msukserver.net/Dev/ItemSwitcher/?l=domain1">
                    Theme Forest
                    <span class="orange">Orange</span>
                    </a>
                </li>
            	<li class="is-nav-li">
                	<a href="http://msukserver.net/Dev/ItemSwitcher/?l=2">
                    Code Canyon
                    <span class="blue">Blue</span>
                    </a>
                </li>
            	<li class="is-nav-li">
                	<a href="http://msukserver.net/Dev/ItemSwitcher/?l=domain3">
                    Graphic River
                    <span class="green">Green</span>
                    </a>
                </li>
            	<li class="is-nav-li">
                	<a href="http://msukserver.net/Dev/ItemSwitcher/?l=domain4">
                    Video Hive
                    <span class="pink">Pink</span>
                    </a>
                </li>
	';

// STEP 3: DEFINE EACH URL

$l = NULL;
if(isset($_GET['l']) && $_GET['l'] == "domain1"){
  $l = 'http://www.domain1.net/';
}
$l = NULL;
if(isset($_GET['l']) && $_GET['l'] == "domain2"){
  $l = 'http://www.domain2.net/';
}
$l = NULL;
if(isset($_GET['l']) && $_GET['l'] == "domain3"){
  $l = 'http://www.domain3.net/';
}
$l = NULL;
if(isset($_GET['l']) && $_GET['l'] == "domain4"){
  $l = 'http://www.domain4.net/';
}

echo $l;

?>

then the main index.php file which includes settings.php before the header

<?

include 'settings.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>Untitled Document</title>

<link rel="stylesheet" type="text/css" media="screen" href="is/css/<? echo $color; ?>.css"/>
    <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>

</head>

<body>

<div id="isbar" class="isbar">
<div id="left">
	<div class="logo"></div>
</div>
<div id="right">
	<a id="close-button" class="close" href="#hello">
		<p class="close">close</p>
	</a>
	<a class="buy" href="#hello">
		<p class="buy">Purchase</p>
	</a>
</div>
<div id="center">
    	<div id="is-button">
        	<p class="button">Select A Theme</p>
        </div>
    	<div id="is-menu">
        	<ul id="is-nav-ul">
            <? echo $menu; ?>
            </ul>
        </div>
</div>
</div>

<!-- JS -->

<script type="text/javascript">
$("#is-button").click(function () {
$("#is-menu").fadeToggle("slow");
});    
$("#close-button").click(function () {
$("#isbar").fadeOut("fast");
});    
</script>

<iframe src="<? echo $l; ?>" scrolling="yes" width="100%" height="100%">
</iframe>

</body>
</html>

when selecting the link (which navigates to ?l=domain1 (for example))

nothing loads in the iframe, it doesn't seem to be echoing a value for 'l'

all help apperciated
