title: GA Ecommerce tracking data not being sent
body: <p>I have the following ecommerce tracking code. I am making use of multiple trackers. The pageviews are getting tracked correctly but when I view the ecommerce reports no data is coming through. What am I missing?</p>
  
  <pre><code>(function (i, s, o, g, r, a, m) {
      i['GoogleAnalyticsObject'] = r;
      i[r] = i[r] || function () {
          (i[r].q = i[r].q || []).push(arguments)
      }, i[r].l = 1 * new Date();
      a = s.createElement(o),
          m = s.getElementsByTagName(o)[0];
      a.async = 1;
      a.src = g;
      m.parentNode.insertBefore(a, m)
  })(window, document, 'script', '//www.google-analytics.com/analytics.js', 'ga');
  
  ga('create', 'UA-34658431-1', 'auto', {'name' : 'primary'}); // primary tracker
  ga('create', 'UA-64375824-1', 'auto', {'name': 'secondary'});  // secondary tracker.
  
  ga('secondary.send', 'pageview');
  ga('primary.send', 'pageview');
  
  ga('primary.require', 'ecommerce');
  ga('secondary.require', 'ecommerce');
  //ga('primary.ecommerce:clear');
  //ga('secondary.ecommerce:clear');
