2 Scripting Errors I need help fixing!!

// Here's the basic car script described in my tutorial at www.gotow.net/andrew/blog. // A Complete explaination of how this script works can be found at the link above, along // with detailed instructions on how to write one of your own, and tips on what values to // assign to the script variables for it to work well for your application.

// Contact me at Maxwelldoggums@Gmail.com for more information.

// These variables allow the script to power the wheels of the car. var FrontLeftWheel : WheelCollider; var FrontRightWheel : WheelCollider;

// These variables are for the gears, the array is the list of ratios. The script // uses the defined gear ratios to determine how much torque to apply to the wheels. var GearRatio : float[]; var CurrentGear : int = 0;

// These variables are just for applying torque to the wheels and shifting gears. // using the defined Max and Min Engine RPM, the script can determine what gear the // car needs to be in. var EngineTorque : float = 600.0; var MaxEngineRPM : float = 3000.0; var MinEngineRPM : float = 1000.0; private var EngineRPM : float = 0.0;

function Start () { // I usually alter the center of mass to make the car more stable. I'ts less likely to flip this way. rigidbody.centerOfMass.y = -1.5; }

function Update () {

 // This is to limith the maximum speed of the car, adjusting the drag probably isn't the best way of doing it,
 // but it's easy, and it doesn't interfere with the physics processing.
 rigidbody.drag = rigidbody.velocity.magnitude / 250;

 // Compute the engine RPM based on the average RPM of the two wheels, then call the shift gear function
 EngineRPM = (FrontLeftWheel.rpm + FrontRightWheel.rpm)/2 * GearRatio[CurrentGear];
 ShiftGears();

 // set the audio pitch to the percentage of RPM to the maximum RPM plus one, this makes the sound play
 // up to twice it's pitch, where it will suddenly drop when it switches gears.
 audio.pitch = Mathf.Abs(EngineRPM / MaxEngineRPM) + 1.0 ;
 // this line is just to ensure that the pitch does not reach a value higher than is desired.
 if ( audio.pitch > 2.0 ) {
     audio.pitch = 2.0;
 }

 // finally, apply the values to the wheels. The torque applied is divided by the current gear, and
 // multiplied by the user input variable.
 FrontLeftWheel.motorTorque = EngineTorque / GearRatio[CurrentGear] * Input.GetAxis("Vertical");
