Where Is My Error In My Zombie Cloning Script? - (Possible for i = 1, do error)

-- Context -- This script is being used to spawn zombies on spawnPads when a BoolValue called ZombiesReady is set to true. When testing the script, my ZombiesReady is set to true correctly, and the ZombiesYTS value is 10, but no zombies are spawning, or even being cloned from the TemplateZombie in the Lighting. There are no errors in the output, I assume the issue is with this snippet of code:

if ZombiesReady.Value == true then ZombiesReady.Value = false for i = 1, ZombiesYTS.Value do wait(math.Random(1, 18) * RoundNum.Value) local Zombie = game.Lighting.TemplateZombie:Clone()

Thanks guys for being so darn good at figuring out whats wrong with my scripts. You guys are the lifeblood of the community, and I am sure you can figure this one out.

while true do
	if ZombiesReady.Value == true then
		ZombiesReady.Value = false
		for i = 1, ZombiesYTS.Value do
			wait(math.Random(1, 18) * RoundNum.Value)
			local Zombie = game.Lighting.TemplateZombie:Clone()
			Zombie.Name = " "
			Zombie.Enemy.MaxHealth = 100 * RoundNum.Value
			Zombie.Enemy.Health = Zombie.Enemy.MaxHealth
			local choices = game.spawnPads:GetChildren()
			local teleportto = (choices[math.random(1,#choices)])
				if teleportto~=nil then
					local torso = Zombie.Torso
					local location = teleportto.Position

					local x = location.x
					local y = location.y
					local z = location.z
				
					x = x
					z = z 
					y = y 

					local cf = torso.CFrame
					local lx = 0
					local ly = y
					local lz = 0
					torso.CFrame = CFrame.new(Vector3.new(x,y,z), Vector3.new(lx,ly,lz))
					Zombie.Parent = game.Workspace
				end 
		end
	end
	wait(.1)
end	

And this is the rest, before the script

local ZombiesKilled = game.Workspace.ZombiesKilled
local ZombiesYTS = game.Workspace.ZombiesYetToSpawn
local RoundNum = game.Workspace.RoundNumber
local ZombiesRequiredToKill = 0
local ZYTSlast = 0
local ZombiesReady = game.Workspace.ZombiesReady

local ZYTSmultiplyer = 1.4

function gameStart()
    print ("Loaded")
    ZombiesYTS.Value = 10
    ZombiesRequiredToKill = ZombiesYTS.Value
    ZombiesKilled.Value = 0
    ZYTSlast = 10
    RoundNum.Value = 1
    wait(3)
    ZombiesReady.Value = true
end

gameStart()

while true do
    if ZombiesRequiredToKill == ZombiesKilled.Value then
        RoundNum.Value = RoundNum.Value + 1
        ZombiesYTS.Value = ZYTSlast * ZYTSmultiplyer
        wait(.1)
        ZYTSlast = ZombiesYTS.Value
        ZombiesRequiredToKill = ZombiesYTS.Value
        ZombiesReady.Value = true 
    end
    wait(.1)
end

Perci1 Solved this in the comments, I just want the post to be solved.
