Integrate tradedoubler to our checkout_success. Will not be able to work on our live shop. We use oscommerce Rc2a. And have tried the contribution: [login to view URL],1637 . But this contribution did not generate the code that Tradedoubler needed. Similar to this: <img src="[login to view URL]$total_cost&orderNumber=auto¤cy=EUR" width="1" height="1" /> (XXXXXX = our org id and event id)
