Hi kamalsomani
don’t know if you’ve sorted this out but first thing, check that the code it appearing in your html (view source, at the bottom of the page)
if not, are you logged into the manager?
the plugin won’t show any code if you’re logged into the manager (so you don’t show in the stats, cool huh!)
if you’re definitely not logged into the manager and it’s not putting any code in your page, double check the instal instructions for the plugin and try again
I’ve just done that and it’s working beautifully

(once I’d sorted the logged in bit... see it’s as cunning as a fox who’s been appointed professor of cunning at Oxford University
hope that helps
