18:53:00.664 - Unable to cast double to token
player:WaitForChild("PlayerGui"):WaitForChild("ScreenGui"):WaitForChild("ImageLabel").Visible=true wait(1) game.StarterGui.ScreenGui.ImageLabel:TweenPosition(0.5,-200,0,0)
First argument for TweenPosition in GUIs should always be a UDim2Value which is what you were missing. Second argument "In" can be either "In" or "Out" which will vary how the GuiObject moves. Third argument varies the increments of how the position will change. Fourth (0.5) is the amount of time it takes to reach the designated position. EDIT: Sorry made a typo
player:WaitForChild("PlayerGui"):WaitForChild("ScreenGui"):WaitForChild("ImageLabel").Visible=true wait(1) game.StarterGui.ScreenGui.ImageLabel:TweenPosition(UDim2.new(0.5,-200,0,0),"In","Sine",0.5)
