Output says I have a Bad Argument?

Here is my code: You don't have to read all of it, just read from line 139 and on. Line 139 was given an error (bad argument). You'll see the output under the code. Help?

Code:

  if humanoid and humanoid.Health > 0 then
    table.insert(players, player)
  end
end



message.Value = "Map Being Chosen..."
