$Item->get_permanent_url();
$Item->get('title');
$Item->get('excerpt');

I'm including the code in the _item_block.inc.php file in my custom skin right after the post content (so the user can +1 individual posts). All three are coming up with blank responses. If I use $Item->permanent_url(); I do get the correct url for each post.

The snippets I wrote 'return' values, if you want do display them use this instead

$Item->permanent_url();
$Item->disp('title');
$Item->disp('excerpt');

Example

my title is: <?php $Item->disp('title'); ?>
my title is: <?php echo $Item->get('title'); ?>
