Why is it not showing the option for the next page?

I am using the girdly theme for mobile devices. But for some reason, it is not showing the next page. Any ideas why. Here is the code for the next page as it appears on the index.php:

<?php if (have_posts()) : ?>
<div id="post-area">
<?php while (have_posts()) : the_post(); ?>	

   		<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
		 <?php if ( has_post_thumbnail() ) { ?>
         <div class="gridly-image"><a href="<?php the_permalink() ?>"><?php the_post_thumbnail( 'summary-image' );  ?></a></div>
          <div class="gridly-category"><p><?php the_category(', ') ?></p></div>

		  <?php } ?>
       			<div class="gridly-copy"><h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>
                <p class="gridly-date"><?php the_time(get_option('date_format')); ?>  </p>

<?php the_excerpt(); ?> 

               <p class="gridly-link"><a href="<?php the_permalink() ?>">View more &rarr;</a></p>
         </div>
       </div>

<?php endwhile; ?>
</div>
<?php else : ?>
<?php endif; ?>

<?php next_posts_link('<p class="view-older">View Older Entries</p>') ?>

<?php get_footer(); ?>
