Why wont this save/load multiple values?

local Storage = game:GetService('DataStoreService'):GetDataStore('SkinsHolder')

game.Players.PlayerAdded:Connect(function(player)
	local skins = game.ServerStorage.Lazors:Clone()
	skins.Parent = player
	local savedskins = Storage:GetAsync(player.userId .. "-Skins")
	if savedskins ~= nil then 
		for i,v in pairs(skins:GetChildren()) do
			v.Value = savedskins 
		end
	end
end)

game.Players.PlayerRemoving:connect(function(player)
	local id = player.userId
	for i,v in pairs(player.Lazors:GetChildren()) do
		local skinsvalue = v.Value
		for i,v in pairs(player.Lazors:GetChildren()) do
			Storage:SetAsync(id.. "-Skins",skinsvalue)
		end
	end
end)

Its supposed to save the values(which are bool values) and load them if they are true or false. Why will this not work?

Your problem is that you are setting the value for all of them with the value from one skin. The best way to fix this is to use a table in a fashion somewhat like this:

local Storage = game:GetService('DataStoreService'):GetDataStore('SkinsHolder')

game.Players.PlayerAdded:Connect(function(player)
	local skins = game.ServerStorage.Lazors:Clone();
	skins.Parent = player;
	local savedskins = Storage:GetAsync(player.UserId .. "-Skins");
	if savedskins == nil then
                warn("Data not found");
        else
		for i,v in pairs(skins:GetChildren()) do
			v.Value = savedskins[i]; 
		end;
	end;
end);

game.Players.PlayerRemoving:connect(function(player)
	local id = player.UserId;
	local skins = {};
	for i,v in pairs(player.Lazors:GetChildren()) do
		table.insert(skins, i, v.Value); -- This inserts into the skins table and sets the value of v to i (the index of the object)
	end;
	Storage:SetAsync(id.. "-Skins", skins);
end);

I hope this helped. If it did please accept this as the answer. If you are still confused or just need help with other scripts feel free to message me and ask.
