谷歌分析电子商务跟踪问题

我已经在我的网站和谷歌分析设置了电子商务跟踪。问题是,有时它跟踪电子商务的销售,但有时却没有。

下面是在结束正文标记之前输出的代码:

<!-- BEGIN GOOGLE ANALYTICS CODE -->
<script type="text/javascript">
//<![CDATA[
    var _gaq = _gaq || [];
    _gaq.push(["_setAccount", "UA-2795368-10"]);
    _gaq.push(["_trackPageview", "/checkout/onepage/success/"]);

    (function() {
        var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
        ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
        (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(ga);
    })();
//]]>
</script>
<!-- END GOOGLE ANALYTICS CODE -->
        <script type="text/javascript">
//<![CDATA[
_gaq.push(["_addTrans","100000029","","10.0000","0.0000","0.0000","asa","","GB"]);
_gaq.push(["_addItem","100000029","12","Test Item","","10.0000","1.0000"]);
_gaq.push(["_trackTrans"]);
//]]></script></div>
