How to save get_pages custom meta field select value

Hello,

I have created a custom meta field that displays a list of the published pages in a select field.

I am struggling to save and display the values when the page has been saved.

The code using to generate the select options

$item_section_two_link = get_post_meta ($post->ID, 'item_section_two_link_field', true ); 

    $posts = get_pages(array('post_type'=> 'page', 'post_status'=> 'publish', 'suppress_filters' => false, 'posts_per_page'=>-1));
    echo '<select name="item_section_two_link_field" id="'.$select_id.'">';
echo '<option value = "test" >All '.$label.' </option>';
	foreach ($posts as $post)
{
            echo '<option value="', $item_section_two_link, '"', $selected == $post->ID ? ' selected="selected"' : '', '>', $post->post_title, '</option>';
        }
    echo '</select>'; ?>

I use save_post to save tehother meta boxes (text, textarea etc) but can’t save the select field – code below

if ( ! isset( $_POST['item_section_two_link'] ) ) {
		return;
	}
	$item_featured_link_save = ( $_POST['item_section_two_link'] );
	update_post_meta( $post_id, 'item_section_two_link_field', $item_featured_link_save );

Any help much appreciated

Thanks
