I got this script but where do I place it? I want script to spawn zombie every 10 sec in place.

I got this script but where do I place it?

local Zombie = game:GetService("ReplicatedStorage").Zombie

while wait(10) do
      Zombie:Clone().Parent = workspace
end

This not working :/.

Basicly I got this script from here in scripting helpers by a guy called 3chars20 but I do not know where to place it and this is not working.

This is supposed to spawn a NPC Zombie to workspace every 10 seconds. I do not understand this please help.

You can place it in ServerScriptService or Workspace. Also make sure your NPC's name is set to "Zombie" and make sure you put it in ReplicatedStorage. That is all :).
