[SOLVED] Invalid argument #1 to 'pairs' (table expected, got Instance) ?

Hey guys need yall help with this i kept getting this error,

Also I'm using a module script, if you can help out i appreciate it.

local ZSModule = {}
function ZSModule.movezombieto(zom, pathtable, pos)
	local wal = zom:WaitForChild("Humanoid"):LoadAnimation(zom:WaitForChild("Config"):WaitForChild("WalkAnim"))
	wal.Priority = Enum.AnimationPriority.Action
	wal:Play()
	spawn(function() zombiehealthcheck(zom) end)

	spawn(function() 
		repeat wait(math.random(5,50)) 
			if zom:WaitForChild("Humanoid").Health > 0 then 
				zom:WaitForChild("Config"):WaitForChild("ZombieRawr"):Play()
				wait(math.random(4, 8))
				zom:WaitForChild("Config"):WaitForChild("ZombieRawr"):Stop()
			end 
		until zom:WaitForChild("Humanoid").Health > 0 
	end)
	for _, pathp in pairs(pathtable) do --Problem
		if zom:WaitForChild("Humanoid").Health > 0 then
			moveTo(zom:WaitForChild("Humanoid"), pathtable.Position)
			zom:WaitForChild("Humanoid").MoveToFinished:Wait()
		end
	end
end

return ZSModule

here's the script's parent or whatever you call it lol (summarised)

local WaveFolder = ServerStorage:WaitForChild("Waves")
local CurrentWave = ReplicatedStorage:WaitForChild("ZombiesFolder"):WaitForChild("CurrentWave")
local pathtable 

zomv = WaveFolder:GetChildren()

		pathtable = workspace:WaitForChild("MapSpawned"):WaitForChild(CurrentMap.Value):WaitForChild("Config"):WaitForChild("Paths")


function NewZombie(ZombieFolder, zomv, pos, parentingto)
	local selectedzombiename = string.split(zomv.Name, " ")
	local selectedzombie = ZombieFolder:WaitForChild(selectedzombiename[2])
	local zomcount = zomv.Value
	for i = 1, zomcount, 1 do
		if CurrentHealth.Value <= 0 then
			break
		end
		wait(1)
		local clonedzom = selectedzombie:Clone()
		for _, characterPart in pairs(clonedzom:GetChildren()) do
			if characterPart:IsA("BasePart") then
				PhysicsService:SetPartCollisionGroup(characterPart, "Players")
			end
		end
		clonedzom.Parent = parentingto
		clonedzom:MoveTo(pos)
		spawn(function()
			ZSModule.movezombieto(clonedzom, pathtable)
		end)
	end
end


function WaveSystem()
	Alarm:Clone().Parent = Arrow
	for _, wav in pairs(WaveFolder:GetChildren()) do
		if string.match(tostring(CurrentWave.Value), wav.Name) then
			print(CurrentWave.Value, wav)
			if CurrentHealth.Value > 0 then
				Arrow:WaitForChild("Alarm"):Play()
				--for count = 1, wav:WaitForChild("ZombiesSpawn").Value, 1 do
				--	print(count)
				--	wait(1)
					
				--end
				currentwave += 1
				CurrentWave.Value = currentwave

				print(currentwave)
				local currentwavefo = wavetable[currentwave]
				local currentwavefolder = currentwavefo:GetChildren()

				table.sort(currentwavefolder, function(a,b) local aname = string.split(a.Name, " ")[1] local bname = string.split(b.Name, " ")[1] return tonumber(aname)<tonumber(bname) end)
				


				for _, zoms in pairs(currentwavefolder) do
					NewZombie(ZombieFolder, zoms, Start.Position, ZombiesSpawnedFolder)
				end
					

				wait(10)

				CurrentWave.Value = CurrentWave.Value + 1
				RewardPlayersCash = RewardPlayersCash + 50
				for _, plr in pairs(Players:GetPlayers()) do
					plr:WaitForChild("Leaderstats"):WaitForChild("Cash").Value = plr:WaitForChild("Leaderstats"):WaitForChild("Cash").Value + RewardPlayersCash
				end
			else
				LostZ()
				Arrow:WaitForChild("Alarm"):Destroy()
			end
		end
	end
	if CurrentHealth.Value > 0 then
		TriumphZ()
		Arrow:WaitForChild("Alarm"):Destroy()
	else
		LostZ()
		Arrow:WaitForChild("Alarm"):Destroy()
	end
end
