Why I can't destroy the Sword that's on the Players Backpack?

So basically, the Sword is not being destroyed from player's I don't get any kind of errors, anyone knows what am I doing wrong?

local playersPlaying = require(game.ReplicatedStorage.playersPlaying)
local Sword = game.ReplicatedStorage.Tools.Sword:Clone()


script.Parent.MouseButton1Click:Connect(function()
	script.Parent.Parent.Parent.Visible = false
	
	for i, v in ipairs(playersPlaying) do
		local didPlayerUseSword = Instance.new("BoolValue")
		didPlayerUseSword.Name = "didPlayerUseSword"
		didPlayerUseSword.Value = false
		didPlayerUseSword.Parent = v
	end

	for i, v in ipairs(playersPlaying) do
		Sword.Parent = v.Backpack
		v.Backpack.Sword.Activated:Connect(function()
			v.didPlayerUseSword.Value = true
		end)
	end
	
	
	wait(5)
	script.Parent.Parent.Parent.Visible = true
	
	for i, v in pairs(playersPlaying) do
		--KILL PLAYER
		if v.didPlayerUseSword.Value == false then
			v.Character.Humanoid.Health = 0
			table.remove(playersPlaying, i)
		end
			print(v.Name.." Clicked The Tool")
			for i, v in pairs(playersPlaying) do
			local sword = v.Backpack:FindFirstChild("Sword")
			if sword then
	 	    sword:Destroy()
			end
		end	
	end
end)

In your first line, you are using require, which loads a moduleScript. You are trying to make a list of activePlayers. This can be done with:

game.Players:GetChildren()

or by inserting a bool value when players join

game.Players.PlayerAdded:Connect(function(plr)
     local tag = Instance.new("BoolValue",plr)
     tag.Name = "Playing?"
     tag.Value = true
end)

(If this method is used, you'll need to find the value.)

for i,v in pairs(game.Players:GetChildren()) do
     if v:FindFirstChild("Playing?") then
          if v["Playing?"].Value == true then
               --Code here
          end
     end
end

You should also use plr.Backpack:FindFirstChild("Sword") to make sure that the player has a sword. (Of course, the plr part will be whatever you have your player labeled as.)

Other than that, your script is correct.
