How do I print the magnitude between a object, and the player's torso using a localscript?

local Torso = game.Players.LocalPlayer.Character.Torso

local Origin = script.Parent

local Mag = (Torso.Position - Origin.Position).Magnitude

game.Players.PlayerAdded:connect(function(P)
wait(4) --loading time
print(Mag)

end)

I'm trying to write a rendering script but I'm having problems with actually "finding" the distance between the Object and player. And the output will not print anything.

Do local scripts not work client side?

Assistance would be great, Thanks.
