TweenPosition in textlabel won't go down?

wait(2)
local lvl = script.Parent
lvl:TweenPosition(UDim2.new(0,0,1,0), "InOut", "Sine", 0.5)
wait(.5)
lvl:Destroy()

this script is when a text label enters the gui it waits 2 seconds and slides towards the bottom of the screen and dissapears. this local script is in that text label, I've been trying to make it so it slides down but it always slides to the corners of the screen instead of the bottom no matter how many times I change the UDim2 numbers.
