Displaying meta data

Hello

I am wanting to display meta data on my WP site…

I am using a write panel that I have started using a great tutorial I found… my functions file has the following code:

/*
Plugin Name: Custom Write Panel

Description: Allows custom fields to be added to the WordPress Post Page

$new_meta_boxes =
  array(
	  "image" => array(
	  "name" => "image",
	  "std" => "",
	  "title" => "Product Image",
	  "description" => "Enter full path to image here."
	  ),
	  "price" => array(
	  "name" => "price",
	  "std" => "",
	  "title" => "Product Price",
	  "description" => "Only numbers and periods!  DO NOT ENTER \"$\"!"
	  ),
	  "size" => array(
	  "name" => "sizes",
	  "std" => "",
	  "title" => "Available Sizes",
	  "description" => "Enter comma-separated values. (ex: \"Small, Medium, Large\")"
	  ),
	  "colors" => array(
	  "name" => "colors",
	  "std" => "",
	  "title" => "Available Colors",
	  "description" => "Enter comma-separated values. (ex: \"Red, White, Blue\")"
	  ),
	  "catalog" => array(
	  "name" => "catalog",
	  "std" => "",
	  "title" => "Catalog Number",
	  "description" => "Enter catalog number here."
	  ),
	  "cannotbuy" => array(
	  "name" => "cannotbuy",
	  "std" => "",
	  "title" => "Cannot Purchase Online",
	  "description" => "If this is an item that is not allowed to be sold online, type in \"yes\" or \"y\"."
	  ),
	  "sale" => array(
	  "name" => "sale",
	  "std" => "",
	  "title" => "Sale Price",
	  "description" => "Enter in a dollar amount or percentage off - be sure to include the \"$\" or \"%\" symbols."
	  ),
	  "quantity" => array(
	  "name" => "quantity",
	  "std" => "",
	  "title" => "Quantity in Stock",
	  "description" => "Enter in a value for how many items you have in stock."
	  )
  );

function new_meta_boxes() {
global $post, $new_meta_boxes;

foreach($new_meta_boxes as $meta_box) {
$meta_box_value = get_post_meta($post->ID, $meta_box['name'].'_value', true);

if($meta_box_value == "")
$meta_box_value = $meta_box['std'];

echo'<input type="hidden" name="'.$meta_box['name'].'_noncename" id="'.$meta_box['name'].'_noncename" value="'.wp_create_nonce( plugin_basename(__FILE__) ).'" />';

echo'<h2>'.$meta_box['title'].'</h2>';

echo'<input type="text" name="'.$meta_box['name'].'_value" value="'.$meta_box_value.'" size="55" /><br />';

echo'<p><label for="'.$meta_box['name'].'_value">'.$meta_box['description'].'</label></p>';
}
}

function create_meta_box() {
global $theme_name;
if ( function_exists('add_meta_box') ) {
add_meta_box( 'new-meta-boxes', 'Course Information', 'new_meta_boxes', 'post', 'normal', 'high' );
}
}

function save_postdata( $post_id ) {
global $post, $new_meta_boxes;

foreach($new_meta_boxes as $meta_box) {
// Verify
if ( !wp_verify_nonce( $_POST[$meta_box['name'].'_noncename'], plugin_basename(__FILE__) )) {
return $post_id;
}

if ( 'page' == $_POST['post_type'] ) {
if ( !current_user_can( 'edit_page', $post_id ))
return $post_id;
} else {
if ( !current_user_can( 'edit_post', $post_id ))
return $post_id;
}

$data = $_POST[$meta_box['name'].'_value'];

if(get_post_meta($post_id, $meta_box['name'].'_value') == "")
add_post_meta($post_id, $meta_box['name'].'_value', $data, true);
elseif($data != get_post_meta($post_id, $meta_box['name'].'_value', true))
update_post_meta($post_id, $meta_box['name'].'_value', $data);
elseif($data == "")
delete_post_meta($post_id, $meta_box['name'].'_value', get_post_meta($post_id, $meta_box['name'].'_value', true));
}
}

add_action('admin_menu', 'create_meta_box');
add_action('save_post', 'save_postdata');

?>

My problem is that the meta – displayed using : <?php the_meta(); ?> in single.php displays the data thusly:

price_value: 4

Where I want it to read

Price: 4

As seen on the site im making: here

Any help appreciated!
