charecter controller not responding to input

hi,
i’m using unity 5.1.1 and i have downloaded the standard assets package from the unity store.after creating a simple and flat terrain i placed a first person character controller into the scene, but it does not respond to anything, neither mouse movement nor key presses on keyboard i also checked if the firstpersoncontroller script is applied to it and it is.
after switching to game mode it just drops down and the default drop sound plays but does not respond to any input.

Check if the script requires public variables (maybe “public GameObject player;” or something).
Maybe you have to assign the player to the variable of the script.
