Can You help me on making a script that does this?

How do you make a script that when a your mouse points at a player it shows his name.

mouse = GetMouse:()
name = game.Players.LocalPlayer.Name

if game.Players.LocalPlayer.Character.Torso.mouse.MouseOver then
nameshow = Instance.new("ScreenGui")
nameshow2 = Instance.new("TextLabel")
nameshow2.Parent = nameshow
nameshow2.Text = name	
end

I'm not a scripting genius, but I'm sure this will work.
