[SOLVED] My car's wheels are not working properly! What should I do?

So I was making a car chassis with good physics and I completed the model of the car. Then I created a vehicle seat and put the following script inside:

-- get the specifications
local speed         = script.speed.Value
local accleration   = script.acceleration.Value
local steeringspeed = script.steeringSpeed.Value
local steeringangle = script.steeringAngle.Value

-- set up the shortcuts
local vehicle   = script.Parent.Parent
local seat      = script.Parent

-- find the tires
local A         = vehicle.A     -- front left
local AA        = vehicle.AA    -- front right
local B         = vehicle.B     -- back left
local BB        = vehicle.BB    -- back right

-- find the steering mechanism
local steerA    = vehicle.SteeringA.Servo
local steerB    = vehicle.SteeringB.Servo


-- set up wheels' motor accerlation
A.Motor.MotorMaxTorque      = accleration
AA.Motor.MotorMaxTorque     = accleration
B.Motor.MotorMaxTorque      = accleration
BB.Motor.MotorMaxTorque     = accleration

while true do

    -- power the wheels
    velocity = seat.Throttle * speed -- use the seat's throttle to determine the wheels' action (backward? forward? nothing?)
    A.Motor.AngularVelocity     = velocity
    AA.Motor.AngularVelocity    = velocity
    B.Motor.AngularVelocity     = -velocity
    BB.Motor.AngularVelocity    = -velocity

    wait()

    -- steering
    steering = seat.Throttle * speed
    steerA.AngularSpeed = steeringspeed
        steerA.ServoMaxTorque = 100000000
        steerA.TargetAngle = steeringangle*seat.Steer
    steerB.AngularSpeed = steeringspeed
        steerB.ServoMaxTorque = 100000000
        steerB.TargetAngle = steeringangle*seat.Steer
end

What happens when I run the game is that the steering wheels turn the opposite direction when I turn right or left. This means that I cannot control the car!

The vehicle seat also has number values that represent the following from the above code:

local speed         = script.speed.Value
local accleration   = script.acceleration.Value
local steeringspeed = script.steeringSpeed.Value
local steeringangle = script.steeringAngle.Value
