My datastore wont Save/Load, I have tried many things. How can I solve this problem?

I have been trying different variations of code and viewed many hours on forums and Youtube videos on data stores and still am confused. I have done 2 datastores for cloning and level-stats and they work flawless, not sure why this is different.

I want the IronSword.Value to be saved and loaded on join and leave... The pcall prints that it's saving and loading but the value goes back to 0.

local DataStoreService = game:GetService("DataStoreService")
local Data = DataStoreService:GetDataStore("Stats")
local Store = DataStoreService:GetDataStore("StoreItems") 

local function onPlayerJoin(player)
	

	

	local leaderstats = Instance.new("IntValue")  

	leaderstats.Name = "Storage"

	leaderstats.Parent = player



	local inv = Instance.new("Folder") 

	inv.Name = "Inventory"

	inv.Parent = leaderstats
end

	local weapons = game.ReplicatedStorage.Weapons
	game.Players.PlayerAdded:Connect(function(plr)
	
	local saveditems = plr.Storage.Inventory:WaitForChild("IronSword").Value
	local success, err  = pcall(function()
		Store:GetAsync(plr.UserId.."-Values", saveditems)
	end)

	print(saveditems)
	if success then
		print("value loaded")
	else
		print("value failed to load")
	end
	
	
	while true do
		local saveditems = plr.Storage.Inventory:WaitForChild("IronSword").Value
		wait(10)
		print(saveditems)
		Data:SetAsync(plr.UserId.."-Values", saveditems)
	end
	
	
	
	end)

-----------------------------------------------------------------------------	
	
	game.Players.PlayerRemoving:Connect(function(plr)
	

	local savedval = plr.Storage.Inventory:WaitForChild("IronSword").Value
	local success,  err  = pcall(function()
		Store:SetAsync(plr.UserId.."-Values", savedval)
	end)																				

	print(savedval)
	if success then
		print("value saved")
	else
		print("value failed to load")
		warn(err)
	end


end)

game.Players.PlayerAdded:Connect(onPlayerJoin)


game:BindToClose(function()
	wait(2)

end)

I want the IronSword.Value to be saved and loaded on join and leave... The pcall prints that it's saving and loading but the value goes back to 0.
