Ok, so here's the situation. The main marketing site is WordPress setup on the main www domain, so I have the main Google Analytics profile setup for this. But, our client portal that processes orders, is setup on a sub-domain (portal.domain.com). To setup ecommerce tracking in Google Analytics, should I setup a new profile under the main domain profile, and use the new UA number to track ecommerce - OR - should we enable ecommerce for the main profile? Would appreciate your input.
always save the original profile as a backup.
that said, this is an easy problem to solve. you just need to use this line of code above the "trackpageview" line....
