How could I make it so If touched changes Camera angle and field of view?

I'm trying to make a script that when the player walks through the door it changes their angle of view and etc. The first script is the "CameraChange" and the second one is in the door.

local offset = Vector3.new(50,10,0)
local fieldOfView = 100
local player = script.Parent.Parent
local camera = game.Workspace.CurrentCamera
local runService = game:GetService("RunService")

camera.FieldOfView = fieldOfView
local function onRenderStep()

local playerPosition = player.Character.HumanoidRootPart.Position
local cameraPosition = playerPosition + offset
camera.CoordinateFrame = CFrame.new(cameraPosition, playerPosition)
end

runService:BindToRenderStep('Camera', Enum.RenderPriority.Camera.Value, onRenderStep)

script.Parent.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") ~= nil then
local NewCam = game.Players:GetPlayerFromCharacter(hit.Parent).StarterPlayer.StarterPlayerScripts:WaitForChild("CameraChange")

     NewCam.Disabled = false    
end
