My 173 Script Wont Work When Published, It just doesn't move, when i look away, can anybody help?

the script i have, or when i publish it, doesn't work, like lets say i publish it as a game, the script doesnt work what i want it to do is, move when i'm not looking, it does that if i dont publish it, but when i publish it it just doesn't move, it does nothing

local DIST = 50 -- How many studs for SCP-173 to notice somebody.
local BLOOD = "Blood" -- The name of the 'Blood' decal, for cleaning.

local pTest = Instance.new('Part') -- Test part, never initialized to world space
pTest.Anchored = true

local move = true
local oldpos = nil

		local por = game:GetService('Workspace'):FindPartOnRay(ray,target.Parent,false)
		return (por == nil) or (por:IsDescendantOf(script.Parent.Parent))
	end
	return false
end

works if i dont publish it.
