Google Analytics not tracking transactions

I'm having trouble getting Google Analytics to track transactions for commerce. Here's the code I'm generating on my order confirmation page.

I don't know how to debug this either, I can't find information on how to get error codes out of google's js. I'd run it in firebug's console if I could. At this point I'm stuck on how to proceed.

<script type="text/javascript">
    var _gaq = _gaq || [];
    _gaq.push(['_setAccount', 'UA-########-#']);
    _gaq.push(['_setDomainName', '.mydomain.com']);
    _gaq.push(['_trackPageview']);


    _gaq.push(['_addTrans',
      '117',           // order ID - required
      'StoreName.com',  // affiliation or store name
      '35.96',          // total - required
      '0',           // tax
      '0',              // shipping
      '',       // city
      '',     // state or province
      ''             // country
    ]);
    _gaq.push(['_addItem',
      '117',           // order ID - required
      '1',           // SKU/code - required
      '1 Pack',        // product name
      'Catagory5',          // catagory   
      '35.96,          // unit price - required
      '1'               // quantity - required
    ]);
    _gaq.push(['_trackTrans']);

  (function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
    ga.src = ('h开发者_C百科ttps:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
    (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(ga);
  })();
</script>

Thank you for any suggestions.
