How would I change this gui's position based on the mouse's position?

There is an error in this script. This gui should move to the Mouse's X position. I'm using scale, It could also be offset through. Please help!

local mouse = game.Players.LocalPlayer:GetMouse()
while wait() do
	script.Parent.Position.X.Scale = mouse.X --The error is on line 3.
end

There is no output.

FIXED.

Here is the fixed script. I fixed it myself.

local mouse = game.Players.LocalPlayer:GetMouse()
while wait() do
	script.Parent.Position = UDim2.new(0, mouse.X,0.65, 0)
end
