How do I turn into a Werewolf in Skyrim?

I've already worked out how to become a werewolf (join the companions, join the circle etc). I have the Beast form in my powers list. I just can't seem to activate it - when I select it nothing happens. I have not been able to turn into a werewolf since the first uncontrolled transformation after the blood ceremony.



Any ideas any Skyrim players out there (I know there are lots of you...).How do I turn into a Werewolf in Skyrim?
I don't have werewolf form yet but i'm on that quest, I assume you activate it like a Thu'um

I think you use LB if you have a shout equipped, if you do not have a shout equipped use RB

Not sure about PS3, try googling it.
