access first person controller from other script

hey i am creating a multiplayer game using appwarp and i am using its sample to understand its mechanics. i one of its scripts,it accesses a variable present in the third person controller script by using the following code:-

 ThirdPersonController ctr = GetComponent<ThirdPersonController>();
         ctr.isRemotePlayer = false;

i tried converting it to first person by using this:-

 FirstPersonController ctr=GetComponent();
 ctr.isRemotePlayer = false;

but it says " The type or namespace name `FirstPersonController' could not be found. Are you missing a using directive or an assembly reference?"

Please help!
