How can I display the author with link in the tagview just like in the item view?

I tried adding the following but there was an error:


<?php if($this->item->params->get('itemAuthor')): ?>
<!-- Item Author -->
<span class="itemAuthor">
<?php echo K2HelperUtilities::writtenBy($this->item->author->profile->gender); ?>
<?php if(empty($this->item->created_by_alias)): ?>
<a rel="author" href="<?php echo $this->item->author->link; ?>"><?php echo $this->item->author->name; ?></a>
<?php else: ?>
<?php echo $this->item->author->name; ?>
<?php endif; ?>
<br>
<?php endif; ?>

AWESOME thanks!!!
