Elevator Fails to Open in Servers?

I use the script below in a button to open a two-door elevator, which the doors move in the same direction. It works as intended in test servers (which seems to be a theme that runs through my questions), but in an active server, it fails to operate. The Click Detector noted is in the correct placement, and there is nothing else for the script to do. Any reason why it may be acting up?

-- Door variables
local Button = script.Parent
local Door1 = script.Parent.Parent.Door1
local Door2 = script.Parent.Parent.Door2

function onClicked()
    wait(3)
    for e = 2,25 do
        Door1.CFrame = CFrame.new(Door1.CFrame.x,Door1.CFrame.y,Door1.CFrame.z - 0.15)
        Door2.CFrame = CFrame.new(Door2.CFrame.x,Door2.CFrame.y,Door2.CFrame.z - 0.3)
        wait(.0001)
    end
    wait(5)
    for e = 2,25 do
        Door1.CFrame = CFrame.new(Door1.CFrame.x,Door1.CFrame.y,Door1.CFrame.z + 0.15)
        Door2.CFrame = CFrame.new(Door2.CFrame.x,Door2.CFrame.y,Door2.CFrame.z + 0.3)
        wait(.0001)
    end
end

script.Parent.ClickDetector.MouseClick:connect(onClicked)
