Google Analytics for Multisite Plugin issue

Hi

I have Google Analytics for Multisite plugin installed on the main site.

I have entered the UA code on the network wp-admin settings for the plugin.

After 2 weeks it has only recorded traffic for the main site. Not the 34 multisites connected to it.

Do I have to enter this same code 34 times?

I believe it is meant to work automagically!

Cheers,

Johnny
