Mecanim Animator not showing play bar

I've followed the following tutorial http://www.youtube.com/watch?v=Xx21y9eJq1U to learn about mecanim, and I was able to successfully create the animation and use it in the script as well. However, when in game mode, I do not see the state transition play loops (displayed as green progress bar under each state in the Animator windows). I'm also NOT using unity pro.
