Blogger Template Change Kills Google Analytics Script

For some reason, several categories of Google Analytics tracking my Blogger blog stats have flatlined within the last month or so.

I just realized why, I'd made some template changes, including choosing a different template from among Blogger's selections, and this clobbered the analytics script! 

Strangely, even though the tracking code was nonexistent, the Tracking Status indicator in Analytics still says that it's "Receiving Data" even though statistics like New Visits, Avg. Time on Site, and Bounce Rate have been flat.

Anyway, you can visit this Google Analytics help page to find out how to enter the necessary tracking code (the preferred one to use is asynchronous).
