Typical "Script running ok in studio but not in server tests" problem, help?

Yes, filtering enabled is off

1. should add a blur and a GUI when a player joins, it only shows the gui but not the blur

game:GetService("Players").PlayerAdded:Connect(function(player)  
  local Blur = Instance.new("BlurEffect")
  Blur.Parent = workspace.CurrentCamera
  local ernie = player.PlayerGui:WaitForChild("Password")
  ernie.Enabled = true
end)

1. Should pop up a gui when touched the parent, again, filtering enabled is off

local Fire = game.ServerStorage:FindFirstChild("Fire")

script.Parent.Touched:Connect(function(hit)
local Player = game.Players:GetPlayerFromCharacter(hit.Parent) -- Returns the Player associated with the given character, or nil if the character is not controlled by a player.
   if Player then
	  print(Player.Name)
	  local playercharacter = hit.Parent.Name
	  local player = game.Players:FindFirstChild(playercharacter)
	  local gui = player.PlayerGui.GetEssence
	  Fire:FireServer()
	  gui.Enabled = true
   end
end)

Im currently testing, ill edit is something more appears.

Thanks anticipatedly, SuVee.
