Catchable Fatal Error

Hey Guys,

The problem can be seen here:

http://collossalpixe...io/portfolio-1/

The code for this page is as follows:

<?php /*Template Name: Portfolio - Single*/
?>

<?php get_header(); ?>

<?php if (have_posts()) : ?>

<?php while (have_posts()) : the_post(); ?>

   <h2><?php the_title(); ?></h2>

   <?php the_content('Read the rest of this entry »'); ?>

   <?php   	
       $custom = get_post_custom($post->ID);
       $customer = $custom["client"][0];
       $website_url = $custom["website_url"][0];
   ?>  

   <div class="details">   			
       <h3>Details</h3>
       <div>Client: <span><?=$customer?></span></div>
       <div>URL: <span><a href="<?=$website_url?>"><?=$website_url?></a></span></div>
       <div class="services"><?php echo get_the_term_list( $post->ID, 'servicesRendered', 'Services Rendered: <ul><li>','</li><li>','</li></ul>' ); ?>
       </div>
   </div>
<?php endwhile; ?>
<?php endif; ?>
<?php get_footer(); ?>

Thanks,

Ali
