Hey Rochelle, Yep you have stumbled upon a serious limitation using closed loop reporting. This is what is happening. Since you have sent your email out from the tradeshow campaign, Eloqua is dynamically adding the elqCampaignID of the tradeshow campaign to the links in the email. So when someone clicks on the link, they are inheriting the elqCampaignId linked to the tradeshow. For instance this is an example fo the link that is dynamically generated:
http://<yourhypersite>/LP=312?elqCampaignId=467
In this instance the tradeshow campaign is associated with 467 but your webinar campaign may be linked to 468.
The way to work around this it to take the ELQ ID associated with the webinar campaign and hard code it into the email that you are sending. So you take
http://<your hypersite>/lp=312?elqCampaignID=468 and you hard code that into your email that you are sending out. What happens is Eloqua will then dynamically append the other elqID onto the tail end so you get this:
http://<your hypersite>/lp=312?elqCampaignID=468&?elqCampaignID=467. Fortunately, for the purposes of CLR it will take the first elqCampaignID it comes across.
