 * Hi there,
 * I have a question, I am building a custom post type for my portfolio area on 
   my website. This is all working out very nice, but now I am running in to the
   following problem. I am using Custom Fields to Echo portfolio specification in
   a [ul] [li], to do this I copy’d and edited to following code form the wordpres
   codex site :
 *     ```
       <ul>
         <?php
             $custom_fields = get_post_custom();
             $specificaties = $custom_fields['specificaties'];
             foreach ( $specificaties as $key => $value ) {
               print " <li> " . $value . "</li>";
             }
         ?>
       </ul>
       ```
   
 * I edited it so it would not show the Value ID, but now the problem is, when a
   item doesnt go any value it gives the following error
 * `Warning: Invalid argument supplied for foreach()`
 * I am not that great with PHP just yet, I am starting to learn it bit by bit. 
   I would say that I need to add something like a ELSE ore something but everything
   I try results in errors.
 * Hope somebody can help me 🙂
 * Kind Regards,
    Wilco
