Google Analytics not tracking orders

Hi Guys I'm using opencart 1.5.2.1

I added my google analytics tracking code into the opencart by going into settings/server/ and adding to the 'google analytics code box'

I can see that visitors are being tracking on my website now in Google analytics, however after clicking on my google shopping add, being directed to my website and then placing my own test order, the order does not appear in Google adwords or Google analytics. So it would appear that something is not tracking correctly as I have 0 orders shown in the ecommerce conversion rate...

Can anyone shed some light on this for me? Is there something I haven't done?

Kind Regards

You would need to add a plug-in / extension for e-commerce data / goal conversions etc.

Thankyou for the reply. Could you recommend one for me?

Kind Regards
