Google analytics commerce tracking issues

I have installed some tracking code on a hotel website I look after. Only problem is that the transactions are not being tracked.

How it should be done per Google

How I have done it - on the thanks page after someone has made the booking:

<script src="http://www.google-analytics.com/urchin.js" type="text/javascript">
</script>
<script type="text/javascript">
_uacct = "UA-xxxxxx-1";
urchinTracker();
</script>
<form style="display:none;" name="utmform">
<textarea id="utmtrans">UTM:T|||
65|||Auckland||New Zealand
UTM:I|||single||65|
1
UTM:I|||double||75|
0
UTM:I|||triple||85|
0
UTM:I|||twin2||80|
0
UTM:I|||twin3||85|
0
UTM:I|||family||110|
0
UTM:I|||suite||100|
0
</textarea>
</form>
<script type="text/javascript">
__utmSetTrans();</script>

HTML:

The sample booking in this instance is for one single room at $65 being in total $65.

Looks correct to me, but I am not seeing the stats come through.

What am I doing wrong.

Thanks.
