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)
