My lever works but it wont go back to its original spot when clicked? (Solved)

I use tweenservice to animate my lever and I have 6 parts in total for my lever, I'm trying to get them to switch back and forth. In my code I programmed it to where it should be able to switch back and forth when clicked but it just stays in the same spot once it gets moved. I apologize for the messy code, I plan to fix it once I can get the code to work.

local SP = script.parent
local D = SP.Demat
local CD = D.Demat.ClickDetector
local isdown = false
local isup = true


local tweenService = game:GetService("TweenService")
local tweeningInformation = TweenInfo.new(
	0.4, -- Time
	Enum.EasingStyle.Bounce, -- Easing Style
	Enum.EasingDirection.InOut, -- Easing Direction
	0, -- Number of times it repeats
	false, -- If it reverts
	0
)
local partProperties = {
	Position = Vector3.new(0.245, 6.523, 54.453)
}
local Tween7 = tweenService:Create(D.Demat, tweeningInformation,partProperties)

local partProperties = {
	Position = Vector3.new(0.497, 6.266, 54.287);
	CFrame = D.Part1.CFrame * CFrame.Angles(0, -30, 0)
}
local Tween8 = tweenService:Create(D.Part1, tweeningInformation,partProperties)

local partProperties = {
	Position = Vector3.new(0.497, 6.266, 54.287);
	CFrame = D.Part2.CFrame * CFrame.Angles(0, -30, 0)
}
local Tween9 = tweenService:Create(D.Part2, tweeningInformation,partProperties)

local partProperties = {
	Position = Vector3.new(0.499, 6.523, 54.454)
}
local Tween10 = tweenService:Create(D.Part3, tweeningInformation,partProperties)

local partProperties = {
	Position = Vector3.new(0.248, 6.523, 54.454)
}
local Tween11 = tweenService:Create(D.Part4, tweeningInformation,partProperties)

local partProperties = {
	Position = Vector3.new(0.009, 6.523, 54.454)
}
local Tween12 = tweenService:Create(D.Part5, tweeningInformation,partProperties)



local partProperties = {
	Position = Vector3.new(0.245, 6.153, 53.309)
}
local Tween = tweenService:Create(D.Demat, tweeningInformation,partProperties)

local partProperties = {
	Position = Vector3.new(0.497, 6.016, 53.615);
	CFrame = D.Part1.CFrame * CFrame.Angles(0, 30, 0)
}
local Tween2 = tweenService:Create(D.Part1, tweeningInformation,partProperties)

local partProperties = {
	Position = Vector3.new(0.008, 6.016, 53.615);
	CFrame = D.Part1.CFrame * CFrame.Angles(0, 30, 0)
}
local Tween3 = tweenService:Create(D.Part2, tweeningInformation,partProperties)

local partProperties = {
	Position = Vector3.new(0.499, 6.156, 53.305)
}
local Tween4 = tweenService:Create(D.Part3, tweeningInformation,partProperties)

local partProperties = {
	Position = Vector3.new(0.248, 6.156, 53.305)
}
local Tween5 = tweenService:Create(D.Part4, tweeningInformation,partProperties)

local partProperties = {
	Position = Vector3.new(0.009, 6.156, 53.305)
}
local Tween6 = tweenService:Create(D.Part5, tweeningInformation,partProperties)



CD.MouseClick:Connect(function()
	if isup == true then
		Tween:Play()
		Tween2:Play()
		Tween3:Play()
		Tween4:Play()
		Tween5:Play()
		Tween6:Play()
		local isup = false
		local isdown = true
	else
		Tween7:Play()
		Tween8:Play()
		Tween9:Play()
		Tween10:Play()
		Tween11:Play()
		Tween12:Play()
		local isup = true
		local isdown = false
	end
end)

If you have figured out the answer yourself, congratulations! But be sure to put Solved in your title.

Never mind, I found out why it didn't work. I fixed it by changing the "isUp" and "isDown" values to IntValues.

free rep plis :3
