Why does my leaderboard datastore not work?

I found out that my datastore was fine, the problem was that in anotehr script I had the wins were updated on the client, where they should be updated on the server.

The value when joining needs to be set to a table in order within the DataStore. The value when leaving needs to be set as an array. Lastly, in the if suc, else statement, don't just print, Run the GetAsync.

datastore = game:GetService("DataStoreService")
WV = datastore:GetDataStore("WinsValue")
game.Players.PlayerAdded:Connect(function(player)
    local folder = Instance.new("Folder")
    folder.Parent = player
    folder.Name = "leaderstats"
    local wins = Instance.new("IntValue")
    wins.Parent = folder
    wins.Name = "Wins"
    ----------------------------
    local winsvalue 
    local suc,err = pcall(function()
        winsvalue = WV:GetAsync(player.UserId) 
    end)
    if suc then
        wins.Value = winsvalue[1]
    else
    local toSave = {wins.Value}
        print("There was an error while trying to get data")
    end
end)
--------------------------------------------------------------------------------------------------------------------------------------------------------
game.Players.PlayerRemoving:Connect(function(player) 
    local suc, err = pcall(function()
        WV:SetAsync(player.UserId, {player.leaderstats.Wins.Value})
    end)
    if suc then
        print("Successfully stored data")
    end
    if err then
        print("There was an error while trying to store data")
    end
end)
