Won't fire the event, and why?

I have a script

MysteryObjects = 0
local items = {"Mysterious Red Rod", "Mysterious Blue Orb", "Mysterious Gold Plate"}

script.Parent.Touched:connect(function(Toucher)
if Toucher.Parent and Toucher.Parent:FindFirstChild("Humanoid") then
Player = game.Players:GetPlayerFromCharacter(Toucher.Parent)
local HasItems = {}
local MysteriousObjects=0
for c,v in pairs(items) do
if Player.Backpack:FindFirstChild(v) and not HasItems[v] then
HasItems[v]= true
MysteriousObjects = MysteriousObjects+1
Player.Backpack:FindFirstChild(v):Destroy()
if v:match("Rod") then
script.Parent.Parent.Rod.Transparency = 0
print('Rod Placed')
elseif v:match("Orb") then
script.Parent.Parent.Orb.Transparency = 0
print('Orb Placed')
elseif v:match("Plate") then
script.Parent.Parent.Plate.Transparency = 0
print('Plate Placed')
end
end 
end


if MysteriousObjects==3 then
print('Staff Built')
wait(15)
game.Workspace["Midnight Moon Shrine"].Beam:Fire()
end
end
end)

Everything works fine, besides the fact you can't be holding the item, and them ore important fact, the last part won't work. It never fires the event nor prints it. Is there something wrong with the way i'm adding?
