Theme options, select multiple

Hi, I got a litle script which display all pages you got in a multiple select on a theme options page. So far everything worked, but when I try want to display the ‘answers’ of that option I got two problems.

1. I retrieve only 1 of all the options I chosen. E.G. I selected page with ID 5,3623 and 23. The layout will only show the latest option ( 23 ). I don’t know if it’s the Framework, or the code I use to retrieve the options.
2. I want to display a “,” after each page ID. Not: 5 3623 23. But : 5,3623,23. Like foreach orso.

FRAMEWORK

<?php 

function mytheme_add_admin() {

global $themename, $shortname, $options ;

if ( $_GET['page'] == basename(__FILE__) ) {

if ( 'save' == $_REQUEST['action'] ) {

foreach ($options as $value) {
update_option( $value['id'], $_REQUEST[ $value['id'] ] ); }

foreach ($options as $value) {
if( isset( $_REQUEST[ $value['id'] ] ) ) { update_option( $value['id'], $_REQUEST[ $value['id'] ]  ); } else { delete_option( $value['id'] ); } }

header("Location: themes.php?page=theme-options.php&saved=true");
die;

} else if( 'reset' == $_REQUEST['action'] ) {

foreach ($options as $value) {
delete_option( $value['id'] ); }

header("Location: themes.php?page=theme-options.php&reset=true");
die;

}
}

add_theme_page($themename." Options", "".$themename." Options", 'edit_themes', basename(__FILE__), 'mytheme_admin');

}

function mytheme_admin() {

global $themename, $shortname, $options;

?>

<div id="wrap">

<form method="post" action="" >

<?php
break;

case 'excludepage':
?>

<select id="topexclude" name="topexclude" multiple="multiple" style="height:150px;">
<?php foreach($news_categories as $page) : ?>
<option name="topexclude" value="<?php echo $page->ID; ?>" <?php if(is_array($val['topexclude']) && in_array($page->ID, $val['topexclude'])) echo ' selected="selected"'; ?>>
<?php echo $page->post_title; ?>
</option>
<?php endforeach; ?>
</select>

<?php break;

}
}
?>

<p class="submit">
<input name="save" type="submit" value="Save changes" />
<input type="hidden" name="action" value="save" />
</p>

</form>

<?php
}
?>

THIS WILL ACTIVE THE EXCLUDEPAGE

<?php

$options = array (

	array(	"name" => "Layout style",
		"id" => "topexclude",
		"desc" => "Click on the pages you want to exclude from the top navigation"
		"type" => "excludepage" ),

);
?>

AND THIS CODE I USE TO SHOW EXCLUDEPAGE

<?php echo get_option('topexclude');?>

I think I need some expert help 😛
