RemoteEvent Script. Works in studio, but not in actual server?

Well, this script works in studio. Opens the door, does what it is meant to do. But however, in a real server, The script doesn't work. It inputs the click detector and all but it just doesn't work. I have filtering enabled turned ON. I tried to follow exactly what Roblox said to do if you have click detectors and filtering enabled.

This script is a serverscript:

wait(1)
local event = Instance.new("RemoteEvent") 
event.Parent = game.Workspace 
event.Name = "LeftDoorEvent"

event.OnServerEvent:connect(function()
	local Door = game.Workspace.LeftDoor1
	local main = Door:GetPrimaryPartCFrame()
	local part = Door.PrimaryPart
	local clic = Door.ClickDetector
	local sound = Door.Sound 
	if Door.Open.Value == 1 then 
		sound:Play()
		local fix = Door.Main.CFrame 
	for i = 0,1.5,0.1 do
		wait(0.05)
		Door:SetPrimaryPartCFrame(Door.Main.CFrame*CFrame.fromEulerAnglesXYZ(0,-0.1,0)*CFrame.new(0.01,0,-0.25))
		Door.Open.Value = 0
		clic.MaxActivationDistance = 0
	end
		Door:SetPrimaryPartCFrame(fix*CFrame.fromEulerAnglesXYZ(0,-math.pi/2,0)*CFrame.new(-2.5,0,-2.5))
		wait(0.25)
		clic.MaxActivationDistance = 15
	elseif Door.Open.Value == 0 then
		sound:Play()
		local fix = Door.Main.CFrame 
	for i = 0,1.5,0.1 do
		wait(0.05)
		Door:SetPrimaryPartCFrame(Door.Main.CFrame*CFrame.fromEulerAnglesXYZ(0,0.1,0)*CFrame.new(-0.01,0,0.25))
		clic.MaxActivationDistance = 0
	end
		Door:SetPrimaryPartCFrame(fix*CFrame.fromEulerAnglesXYZ(0,math.pi/2,0)*CFrame.new(-2.5,0,2.5))
		wait(0.25)
		clic.MaxActivationDistance = 15
		Door.Open.Value = 1
	end 
end)

This is the localscript [which is in replicated first]:

wait(5)
local clickDetector = Instance.new("ClickDetector")
clickDetector.Parent = game.Workspace.LeftDoor1
clickDetector.MouseClick:connect(function(hit)
	game.Workspace.LeftDoorEvent:FireServer()
end)

There is no output error. The only thing that doesn't work is the script in an actual server.
