Transaction cancellation sometimes does not work.

[GoogleCodeExporter]

Hi.

Sometimes clients of our e-store make several identical orders. I've developed 
special page to cancel such duplicates in google analytics. But js code 
provided in google help sometimes not working and duplicate transactions stays 
visible in google analytics report.

Please check following peace of js code, which should cancel transaction. If 
you need more information please let me know. Thank you.

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';
var s = document.getElementsByTagName('script')[0]; 
s.parentNode.insertBefore(ga, s);
})();

(function() {
    var _gaq = window._gaq || [],
        commands = [],
