Spike Trap Script Will Not Tween Objects To CFrame Due To Dictionary Error?

Script Inside Spike Trap Model

What they mean by dictionary is that the last argument of Create needs to be like a table of things to tween, e.g

local Twn = TweenService:Create(Part,TweenInfo.new(2),{CFrame = CFrame.new(1,1,1)})

and "Value" cant be tweened, the properties that can be tweened and can be included in the dictionary are: number bool CFrame Rect Color3 UDim UDim2 Vector2 Vector2int16 Vector3

I think your Up.Value is vector3 right? so just include the Up.Value in the CFrame constructor
