I think i tried this already and it didn't work. But I'll try again just in case. Ero support is useless.
Are you getting subids coming through OK on the Ero reporting end? First step is to figure out where the problem lies.
Cheers Adivity that tracking worked. A rookery mistake on my part.
Would you mind sharing the ero advertising tokens so that I could add ERO Advertising as a predefined traffic source?
I have this from another

The available dynamic parameters are:
[country] Country name
[timestamp] The time when the visitor got redirected (using php time() in seconds)
[domainid] ID of the domain in our system
[campaignid] Campaign ID
[spaceid] Adspace ID
[adid] Advertisement ID
Usage guide:
You have to add the dynamic paramater Smiley: Sleeping Half Moon in the landing page url using ? or &.
Example 1 (landing url without "?"):
Landing page url: http://www.ero-advertising.com/
Landing page with url dynamic parameters: http://www.ero-advertising.com/?country=[country]&ref=[domainid]&time=[timestamp]&campaign=[campaignid]&adid=[adid]
Example 2 (landing url with "?"):
Landing page url: http://www.ero-advertising.com/?id=XXX
Landing page url with dynamic parameters: http://www.ero-advertising.com/?id=XXX&country=[country]&ref=[domainid]&time=[timestamp]&campaign=[campaignid]&adid=[adid]
