Question for the Lab Rats: Trackback

I am in the process of installing a Trackback capability in my blog and have a question for you lab rats who are more blog savvy than me.

Here is what I have done so far:

I am aware that Blogger does not allow for that capability so I googled for a solution and found that one can install Greasemonkey in Firefox, add a userscript for Trackback, and presto: you have Trackback abilities in Blogger.

Indeed, I did exactly that and now above my "compose" box, there is a box where I can enter trackbacks. But every time I go to a website and click on trackback, it takes me to the comment section of that post. I thought I was supposed to obtain a URI to put in the trackback box which then pings the site to let them I included something from their site on my blog. What am I doing wrong?

Anybody? Anybody? Bueller? Bueller?

P.S. To those who have emailed with questions, etc., I am in the process of answering your emails. I am just running a little behind. OK, a lot behind but it has been a bad couple of weeks in terms of organization and getting things done in a timely fashion. ;-)
