UnityException: Input Axis Rotate2 is not setup.

Well... I'm new here, this is my 1st question, here we go. I want to put the first persona controller and I pull the play button and the next error appeared.

"UnityException: Input Axis Rotate2 is not setup." And "UnityException: Input Axis Rotate is not setup."

I'm not a programmer, I'm just want to understand the program and how I have to do for make a "Shooter Game" for my friends.

The question is "What's that?" (Sorry if my english was bad)

See you later! Bye!
