GUI tween is not doing anything (what have I missed?)

local Btn = script.Parent

script.Parent.MouseEnter:Connect(function()    
	    Btn:TweenPosition(UDim2.new(0.25, 0,0.073, 0))

script.Parent.Parent.MouseLeave:Connect(function()
    Btn:TweenPosition(UDim2.new(0.25, 0,0.082, 0))
	end

That is my code. I assume i missed something small that caused the whole thing to not work. The aim of the code is to make an image tween to a position while the mouse is on it, and to tween to the original position when the mouse leaves it. Any help is appreciated!

Use all of the needed parameters for your Tween, which would be:

Btn:TweenPosition(UDim2.new(Position), --The goal positon.
Enum.EasingDirection.YourChoice, --Your EasingDirection
Enum.EasingStyle.YourChoice, --Your EasingStyle
X, --The duration of the Tween in seconds
true/false, -- Whether you want the Tween to interrupt other Tweens
function--  A function you want to call once the Tween is completed(This can also be ignored.)
