Did you not use the Google Analytics module? Templates are smarty templates - thus squiggly brackets must be escaped.
You will need to truncate the jr_jrcore_cache table, and delete data/cache/jrCore/*.tpl and data/cache/ActiveSkin/*.tpl.php files.
I would
highly recommend that you simply use the Google Analytics module.
Hope this helps!
