TweenPosition moving to the wrong place?

so here's the code:

 local ply = game.Players.LocalPlayer
local gui = ply:WaitForChild('PlayerGui'):WaitForChild('ScreenGui'):WaitForChild('Inventory')
local InventoryOpened = false

function onKeyPress(actionName, userInputState, inputObject)
	if userInputState == Enum.UserInputState.Begin then
		print("E was pressed")
		if InventoryOpened == false then
			gui:TweenPosition(UDim2.new({0.15, 0},{0.2, 0}), "InOut", "Quad", 1, true)
			InventoryOpened = true
		else
			print('should close here')
			gui:TweenPosition(UDim2.new({0.15, 0},{1, 0}), "InOut", "Quad", 1, true)
			InventoryOpened = false
		end
	end
end
 
game.ContextActionService:BindAction("keyPress", onKeyPress, false, Enum.KeyCode.E)

The 'Inventory' gui should move to {0.15, 0},{0.2, 0} but for some reason it moves to {0, 0},{0,0}. Also, the gui doesn't close when I press 'E' again.

Any help would be appreciated.
