My script is working, but the tween doesn't play, can I please get some help?

local doorModel = script.Parent

local TweenService = game:GetService("TweenService") local doorTweenInfo = TweenInfo.new( 1, Enum.EasingStyle.Quad, Enum.EasingDirection.Out, 0, false, 0 )

local doorTween = TweenService:Create(doorModel.DoorClosed, doorTweenInfo, {CFrame = doorModel.DoorOpen.CFrame})

doorModel.Square.Touched:Connect(function(hit) if hit.Name == "Key" and hit.BrickColor == doorModel.Square.BrickColor then doorModel.Square.Transparency = 0 hit:Destroy() end end)

doorModel.Triangle.Touched:Connect(function(hit) if hit.Name == "Key" and hit.BrickColor == doorModel.Triangle.BrickColor then doorModel.Triangle.Transparency = 0 hit:Destroy() end end) doorModel.Circle.Touched:Connect(function(hit) if hit.Name == "Key" and hit.BrickColor == doorModel.Circle.BrickColor then doorModel.Circle.Transparency = 0 hit:Destroy() end end)

if doorModel.Circle.Transparency == 0 and doorModel.Square.Transparency == 0 and doorModel.Triangle.Transparency == 0 then
   doorTween:Play()
end
