OC Google analytics

I searched on how to track a website using Google Analytics and then when I tried to add the code via System-Settings-Server, I saw there is no textbox to enter the Google Analytics code. I'm using OC 3.0.02. So, do I need to buy an extension for Google Analytics because is no longer free to add it or what?

go to Extensions -> Analytics -> Google Analytics - edit
and put your code in opened textarea
dont forget status - enabled

If that answers the question please add [SOLVED] to the beginning of this topic title.
