Google Analytic Universal installation

[gedgec]

Hi, I have tried installing the updated Universal Analytics tracking code, however it is not working correctly. I have placed the following code on the receipt page:

<script type="text/javascript"> 
ga('ecommerce:addTransaction', { 
'id': '<actinic:variable name="TheOrderNumber" />', // Transaction ID. Required. 
'affiliation': 'Valucomputers', // Affiliation or store name. 
'revenue': '<actinic:variable name="Total" />', // Grand Total. 
'shipping': '<actinic:variable name="Shipping" />', // Shipping. 
'tax': '<actinic:variable name="Tax1" />', // Tax. 
'currency': 'GBP' // local currency code. 
});

ga('ecommerce:addItem', { 
'id': '<actinic:variable name="TheOrderNumber" />', // Transaction ID. Required. 
'name': '<actinic:variable name="ProdRef" />', // Product name. Required. 
'price': '<actinic:variable name="Price" />', // Unit price. 
'quantity': '<actinic:variable name="Quantity" />' // Quantity. 
});

ga('ecommerce:send'); 
</script>

GA is recording a "conversion" and the 'id' number is pulling through in the source code , but the other variables are not coming through when viewing the source code on the receipt page or in GA.

What I am doing wrong here?

Thanks,
Chris
