Add Dynamic Affiliate ID in Email Using Viral Inviter Script

I'm using the tell a friend script, Viral Inviter. ([login to view URL]) on this page: [login to view URL] And in Viral Inviters back office, I need to dynamically enter the affiliate id of this page in to the emails that go out. In this case the affiliate id is: go Quick video of Viral Inviter admin: [login to view URL] If you have used Viral Inviter before, this should be an easy tweak. Thanks.
