I’v writen down the code, and i get a error message the says "The Variable part_025 has not been assigned in the inspector. I try to drag it like i’m supposed to, but it wont let me. This is the script, those parts are the tires, and i can’t assign them, can you help me?

#pragma strict
var part_027 : WheelCollider;
var part_026 : WheelCollider;
var part_028 : WheelCollider;
var part_025 : WheelCollider;
var maxTorque : float = 50;
function Start () {

}

function FixedUpdate () {
part_025.motorTorque = maxTorque * Input.GetAxis("Vertical");
part_028.motorTorque = maxTorque * Input.GetAxis("Vertical");
part_026.steerAngle = 10 * Input.GetAxis("horizonal");
part_027.steerAngle = 10 * Input.GetAxis("horizonal");
}
