title: Drupal print if single checkbox field is checked
body: <p>I'd like to print something like "yes, checked" if a cck single checkbox is checked.
  The single on/off checkbox has allowed values of no and yes.</p>
  
  <p>checkbox info is - </p>
  
  <pre><code>&lt;input type="checkbox" class="form-checkbox" checked="checked" value="yes"
      id="edit-field-billing-terms-value" name="field_billing_terms[value]"&gt;
  </code></pre>
  
  <p>I'm trying, and failing with modifications of this code - </p>
  
  <pre><code>&lt;?php
    $node-&gt;field_billing_terms[value] . '&lt;br /&gt;';
      if($node-&gt;field_billing_terms[value] == 'yes' ) {
        print "yes, checked";
      }
  ?&gt;
  </code></pre>
  
  <p>Can someone give me some pointers where I'm going wrong? More info can be provided if needed.</p>
