google ecommerce javascript doesn’t work

i need some help with google ecommerce javascript code. As google shows an example of how to implement this function in a website it works fine. But here’s the problem: i need to send data to analytics when asp.net button is pressed, so appropriate way to achieve that is to write javascript function, and place it before </head> tag. here’s the code:

[CODE]<script type=”text/javascript”>
function sendAnalytics(){

var _gaq = _gaq || [];
_gaq.push([‘_setAccount’, ‘UA-27232165-1’]);
_gaq.push([‘_trackPageview’]);
_gaq.push([‘_addTrans’,
‘1334’, // order ID – required
‘Clothing’, // affiliation or store name
‘11.99’, // total – required
‘1.29’, // tax
‘5’, // shipping
‘San Jose’, // city
‘California’, // state or province
‘USA’ // country
]);

// add item might be called for every item in the shopping cart
// where your ecommerce engine loops through each item in the cart and
// prints out _addItem for each
_gaq.push([‘_addItem’,
‘1334’, // order ID – required
‘DDD4’, // SKU/code – required
‘T-bag’, // product name
‘Green Medium’, // category or variation
‘11.99’, // unit price – required
‘1’ // quantity – required
]);
_gaq.push([‘_trackTrans’]); //submits transaction to the Analytics servers

(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’;
var s = document.getElementsByTagName(‘script’)[0]; s.parentNode.insertBefore(ga, s);
})();
return true;
}
</script>[/CODE]

on button click function sendAnalytics() is invoked, but it seems that this part of code doesn’t work, because analytics doesn’t receive any data.

[CODE] (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’;
var s = document.getElementsByTagName(‘script’)[0]; s.parentNode.insertBefore(ga, s);
})(); [/CODE]

any suggestions? Thank you in advance for your help
