This is code:

while true do

You misspelled Children twice on line 94. Made the same mistake.

You put 

zFolder:GetChildern()

instead of 

zFolder:GetChildren()

At line 94 (and some others line) u mispelled :GetChildren to :GetChildern(), changed it in this script:

local MapsFolder = game.ReplicatedStorage:WaitForChild("Maps")
local status = game.ReplicatedStorage:WaitForChild("Status")

while true do
 status.Value = "Intermission 15"
 local interTime = 15
 repeat wait()
  wait(1)
  interTime = interTime - 1
  status.Value = "Intermission "..interTime
 until interTime <= 0
 wait(1)
 status.Value = "Selecting a map"

 local mapId = math.random(1,#MapsFolder:GetChildren())
 local map = MapsFolder:FindFirstChild("Map"..mapId)

 wait(1)
 if map then
  status.Value = "Map has been chosen"

  local mapName = map:FindFirstChild("MapName")
  if mapName then
   status.Value = "The map is: "..mapName.Value
  else

  end
  wait(1)
  status.Value = "Loading map..."

At line 94. You did:

local zFolder = game.ReplicatedStorage:GetChildren("Zombies")
local zombie = zFolder:GetChildern()

What's the "Zombies" inside the :GetChildren()? I'm pretty sure you meant to do wait for child. Try this script:

local MapsFolder = game.ReplicatedStorage:WaitForChild("Maps")
local status = game.ReplicatedStorage:WaitForChild("Status")

while true do
 status.Value = "Intermission 15"
 local interTime = 15
 repeat wait()
  wait(1)
  interTime = interTime - 1
  status.Value = "Intermission "..interTime
 until interTime <= 0
 wait(1)
 status.Value = "Selecting a map"

 local mapId = math.random(1,#MapsFolder:GetChildren())
 local map = MapsFolder:FindFirstChild("Map"..mapId)

 wait(1)
 if map then
  status.Value = "Map has been chosen"

  local mapName = map:FindFirstChild("MapName")
  if mapName then
   status.Value = "The map is: "..mapName.Value
  else
   status.Value = "The map doesn't have a name"
  end
  wait(1)
  status.Value = "Loading map..."

  local newMap
  newMap = map:Clone()
  newMap.Parent = workspace
  newMap.Name = "Map"

  wait(2)

  status.Value = "Teleporting players..."

     local player = 0
     if newMap:FindFirstChild("PlayerSpawns") then
      for i,v in pairs(game.Players:GetPlayers()) do
   local character = workspace:FindFirstChild(v.Name)
   if character then
    local rootPart = character:FindFirstChild("HumanoidRootPart")
    if rootPart then
     local spawnId = math.random(1,#newMap.PlayerSpawns:GetChildren())
        local spawnObj = newMap.PlayerSpawns:FindFirstChild("Spawn"..spawnId)

        if spawnObj then
          player = player + 1
        rootPart.Position = spawnObj.Position
        end
    end
   end
  end
  wait(2)
  status.Value = "The round is starting!"
  wait(2)
  local wave = 1
  local zombies = 0

  repeat wait()
     status.Value = "Wave ".. wave.."!"
    wait(2)

    local waveFolder = game.ReplicatedStorage:WaitForChild("Waves"):FindFirstChild("Waves".. wave)
    if waveFolder then
        for i, v in pairs(waveFolder:GetChildern()) do
            local clone = v:Clone()

            local rootPart = clone:FindFirstChildren("HumanoidRootPart")
            if rootPart then
                clone.Parent = workspace

                local spawnsObj = map:FindFirstChild("ZombieSpawns")
                if spawnsObj then
                    local spawnChild = spawnsObj:GetChildern()

                    local spawnPos = spawnChild[math.random(1, #spawnChild)]

                    if spawnPos:IsA("BasePart") then
                        rootPart.CFrame = spawnPos.Cframe
                        zombies = zombies + 1
                    end
                end
            else
            clone:Destory()
            end
        end
    else
        for i = 1,math.random(wave - 1, wave) do
            local zFolder = game.ReplicatedStorage:WaitForChild("Zombies")
            local zombie = zFolder:GetChildern()[math.random(1,#zFolder:GetChildern())]:Clone()

            local rootPart = zombie:FindFirstChildren("HumanoidRootPart")
            if rootPart then
                local posses = map:FindFirstChild("ZombieSpawns")
            if posses then
                local pos = posses:GetChildren()[math.random(1, #posses:GetChildren())]
                if pos:IsA("BasePart") then
                rootPart.CFrame = pos.CFrame
                zombies = zombie + 1
                 end
             end
         end
      end

       repeat wait() until zombies <= 0
