I can't get Product Purchase Goals to work

I asked some questions about the event format required for Product Purchase Goals in the past, and I thought I had it right. However, recent tests show that they have never fired a goal.

I have two goals set up. One of type 'Product' and one of type 'Event' that is listening to the 'purchase' event (only recently added to test that the event was sent). The product one has never fired a goal, while the event one works fine.

The event I send to trigger the Product and Event goal is in this format:

window.uetq.push('event', 'purchase', {

'transaction_id': '12345',

'ecomm_prodid': ['P1', 'P2'],

'ecomm_pagetype': 'purchase',

'ecomm_totalvalue': 10.000,

'revenue_value': 10.000,

'currency': 'AUD',

'items': [

{'id': 'P1', 'quantity': 1, 'price': 6.000}, 

{'id': 'P2', 'quantity': 1, 'price': 4.000}

]

});

I also send an event for dynamic remarketing:

window.uetq.push('event', '', {

'ecomm_prodid': ['P1', 'P2'],

'ecomm_pagetype': 'purchase',

'ecomm_totalvalue': 10.000,

'revenue_value': 10.000,

'currency': 'AUD'

});

And one for if they use a destination url based goal:

window.uetq.push('event', '', {

'revenue_value': 10.000,

'currency': 'AUD'

});
