This script is only working inside the studio it is not a localscript. Any help?

-- Door variables
local Door 			= script.Parent.Parent.Door.Door 
local DoorLogo 		= Door.DoorLogo 
local DoorSeg 		= Door.DoorSegment 
Door.PrimaryPart 	= Door.DoorSegment

local Open, ShouldBe = false, false
local InZone = {}

-- Door moving function
function Move(O)
	DoorLogo.Moving:Play()
	 for i = 1, 58 do
  		wait(0.01)
		-- Changes the door cframe position.
  		local X, Y, Z = DoorSeg.CFrame.X, DoorSeg.CFrame.Y, DoorSeg.CFrame.Z
  		Door:SetPrimaryPartCFrame(DoorSeg.CFrame * CFrame.new((O and -0.1 or 0.1),0,0))
 	end	
DoorLogo.Moving:Stop()
	DoorLogo.Closed:Play()
end

-- Door parts flashing function
function Flash(Colour)
	if Colour == nil then return end
	for i = 1,2 do
		for i,v in pairs(workspace.SecurityDoor.Door.Door:GetChildren()) do
			if v.Name == "scpl" then
				wait(0.3)
				v.BrickColor = BrickColor.new(Colour)
				wait(0.3)
				v.BrickColor = BrickColor.new("Medium stone grey")
				
			end
		end
	end
end

-- Detect player within zone and flash parts
local sensor = script.Parent.Parent.Door.Sensor
while wait() do
	local shouldOpen = false
	for _, Player in pairs(game.Players:GetPlayers()) do
	if game.Players.LocalPlayer.TeamColor ~= game.Teams["Class-D"].TeamColor or game.Players.LocalPlayer.TeamColor ~= game.Teams["Class-E"].TeamColor then
		if (Player.Character and Player.Character:FindFirstChild("HumanoidRootPart") and (Player.Character.HumanoidRootPart.Position - sensor.Position).magnitude < 10) then
			shouldOpen = true
			break
		end
	end
end
		
	-- Flash parts
	if shouldOpen and not Open then
		Open = true 
		DoorLogo.Beep:Play()
		Flash("Bright green")
		Move(true)
	elseif not shouldOpen and Open then
		Open = false
		Move(false)
		DoorLogo.Beep:Play()
		Flash("Bright red")
	end
