If condition to custom fields

Hi I’m not a PHP programmer therefore I’m do’t realy know what to do.
I got a ready website to maintain and I’m having a problem.
The website is bilingual and right now if I put a document to download in a custom fields it’s the same to both of a languages. I need to insert a code which will allow me to insert a different document to download to each language.

This is the code I have right now.
Thank you!

<?php
/*
* Template Name: Downloads
*/

$allow = (isset($_COOKIE[‘downloads’]) && $_COOKIE[‘downloads’] == 1);

get_header(); ?>
<div id=”main”>
<div class=”content”>
<?php while (have_posts()) : the_post(); ?>
<h1><?php the_title(); ?></h1>
<?php $posts = get_posts(array(‘category_name’ => ‘downloads’, ‘posts_per_page’ => -1)); ?>

<ul class=”investor-list”>
<?php foreach ($posts as $post) : setup_postdata($post); $custom_fields = get_post_custom(); ?>

• <div class=”description-box”>
  <img class=”alignleft” src=”<?php echo get_bloginfo(‘template_directory’). ‘/images/icon-‘ . $custom_fields[‘icon’][0] . ‘.png’; ?>” alt=”” />
  <div class=”description”>
  <h2><?php the_title(); ?></h2>
  <p><?php the_content(); ?></p>
  </div>

  </div>
  <div class=”download-box”>
  ” class=”btn-download”><?php _e(‘Download’, ’tisteron’); ?>
  </div>

<?php endforeach; ?>

<?php endwhile; // end of the loop. ?>
</div>
<aside id=”sidebar”>
<nav class=”main-nav”>
<?php
wp_nav_menu(array(
‘menu’ => ‘Investors’
)); ?>
</nav>
</aside>
</div>

<?php get_footer(); ?>
