You're running X-Cart for your site and you've got Omniture tracking code plugged in all over the place in a global footer. You've got some 70% of all the reports SiteCatalyst can offer, according to something I think I read in one of their manuals once. But you want to integrate the commerce tracking stuff.
So you ask your friendly, neighborhood Internet marketing company to "take care of that" for you.
And suddenly I'm handed a few X-Cart logins.
It looks like the SC code is plugged into a global footer. So it's already there, sans important page-specific variables that I want to insert on the "thank you" page. (Which took some finding all by itself, actually -- the "thank you" page is in the 'Edit Templates' menu under /customer/main/order_message.tpl. Intuitive!)
And then I call you back and say we can't do this for free. An Omniture Implementation Engineer would do it, but I'm a 'third party.'
Suddenly, you're interested in doing it yourself.
It's the circle of life!
