Why doesn't the tween for my sliding door work?

I'm trying to make a sliding door that will either open or close when I click a button. It will open, if I only have the open tweenservice set into place, if I add the close one, it all stops working. Here is my code.

open = true

local TweenService = game:GetService("TweenService")

local door1 = script.Parent.door1


local tweenInfo = TweenInfo.new(2, Enum.EasingStyle.Linear, Enum.EasingDirection.In, 0, false, 0)

local door1Open = Vector3.new(-101.746, 5.52, 17.11)
local door1Close = Vector3.new(-108.172, 5.52, 17.11)

local Open1 = TweenService:Create(door1, tweenInfo, door1Open)
local Close1 = TweenService:Create(door1, tweenInfo, door1Close)

script.Parent.button.ClickDetector.MouseClick:Connect(function()
    if open == true then
        Close1:Play()
        wait(2)
        open = false
    else
        Open1:Play()
        wait(2)
        open = true
    end
end)

If I only have open or close, it works, if I add another one, it all stops working. Help is appreciated.
