"""
Add the necessary tracking information to track each page with Adform.
Add ADFORM_PM to settings. Alternatively you could leave out the pm field and just
write it directly into the template.

<script type="text/javascript">
  {% if feincms_page and feincms_page.adform_id > 0 %}
var _adftrack = {
    pm: {{ feincms_page.adform_pm }},
    id: {{ feincms_page.adform_id }}
};

    var s=document.createElement('script');
    s.type='text/javascript';s.async=true;
    s.src='https://track.adform.net/serving/scripts/trackpoint/async/';
    var x = document.getElementsByTagName('script')[0];
    x.parentNode.insertBefore(s, x);})();
