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.
