Data Store not working to save values in a folder. Help?

So, I need help, this data store script is now working for some reason!

Folder is in "StarterCharacterScripts" The folder has some values in them that are inserted when bought.

I added this following script in the "Workspace":

game.Players.PlayerRemoving:connect(function(player)
    local datastore = game:GetService("DataStoreService"):GetDataStore(player.Name.."Stats") --Player's key.

local statstorage = player.Character:WaitForChild("PlayerSkins"):GetChildren()
for i =  1, #statstorage do
    datastore:SetAsync(statstorage[i].Name, statstorage[i].Value)

end
end)


game.Players.PlayerAdded:connect(function(player)
        local datastore = game:GetService("DataStoreService"):GetDataStore(player.Name.."Stats")

    player:WaitForChild("PlayerSkins")
    wait(1)
    local stats = player.Character:WaitForChild("PlayerSkins"):GetChildren()
    for i = 1, #stats do            
    stats[i].Value = datastore:GetAsync(stats[i].Name)
        end
end)

Everytime I click a button to buy a skin (Wich adds the value to the folder with the id of the skin in it and it works fine. But when I leave the game and come back, it simply doesn't save and my values aren't in the folder. Can someone help me with this? I'd be really apreciated!
