Script deletes itself with an error?

Sorry for the title, the thing kept saying that the title was not specific. I am very confused.

I will explain: This stupid scripting bug makes it so that your script DELETES ITSELF!!! EVEN if there is not code for the script deleting itself PRESENT!!!!!!

This is the error that pops up:

18:52:38.278 - Glitch is not a valid member of Script
18:52:38.279 - Stack Begin
18:52:38.279 - Script 'Workspace.Glitcher', Line 7 - function glitch
18:52:38.281 - Script 'Workspace.Glitcher', Line 42 - function glitch (x5)
18:52:38.281 - Script 'Workspace.Glitcher', Line 47
18:52:38.281 - Stack End

This is the script:

wait(0.1)
local parts = 0
function glitch (m)
	for _,i in pairs (m:GetChildren()) do
		if i:IsA("Part") and not i:FindFirstChild("Glitch") then
			if math.random(1,3) == 1  and not i.Locked then
				local sound = script.Glitch:Clone()
				sound.Parent = i
				sound:Play()
				local ouch = script.GlitchScript:Clone()
				ouch.Parent = i
				ouch.Disabled = false
				--[[
				i.BrickColor = BrickColor.Random()
				i.Size = Vector3.new(math.random(i.Size.X/2,i.Size.X*2),math.random(i.Size.Y/2,i.Size.Y*2),math.random(i.Size.Z/2,i.Size.Z*2))
				if math.random(1,5) == 1 then
					i.Anchored = false
				end
				if math.random(1,5) == 1 then
					local materials = Enum.Material:GetEnumItems() -- Get a table of all the possible materials
					local randomMaterial = materials[math.random(#materials)] -- Select a random value inside the table 
					i.Material = randomMaterial
				end
				if math.random(1,5) == 1 then
					i.Transparency = math.random(1,100)/100
				end
				if math.random(1,5) == 1 then
					i.Reflectance = math.random(1,100)/100
				end
				--]]
				if parts <= 1 then
					parts += 1
				else
					script:Destroy()
				end
			end
		elseif i:IsA("Weld") then
			if math.random(1,3) == 1 then
				i:Destroy()
			end
		else
			glitch(i)
		end
	end
end
while wait() do
	glitch(script.Parent)
end

Can you please help me? Thank you. (If you want the full script look here: https://web.roblox.com/library/5576350053/Glitch-Script maybe another thing is the problem)
