My DataStore script isn't saving, there's no errors in the output? [SOLVED]

This is a Script in ServerScriptService, there are no errors, it just doesn't save.

local DSService  = game:GetService("DataStoreService"):GetDataStore('asdpie')
game.Players.PlayerAdded:Connect(function(plr)
    local stuff = Instance.new("Folder")
stuff.Name = ("sub") 
stuff.Parent = plr

 local Strength =  Instance.new("IntValue")
 Strength.Name = 'Strength'
 Strength.Parent = stuff

local SXP = Instance.new("IntValue")

 SXP.Name = 'SXP'
 SXP.Parent = stuff 
-----------------------SAVE DATA-----------------------
local uniquekey = 'id-'..plr.UserId

local GetSaved = DSService:GetAsync(uniquekey)
if GetSaved then
    Strength.Value = GetSaved[1]

else
    local NumbersForSaving = {Strength.Value}
    DSService:SetAsync(uniquekey,NumbersForSaving)
end
-------------------------------------------------------

SXP.Changed:Connect(function()
    local SXPval = SXP.Value
    if SXP.Value >= Strength.Value * 100 then 
        SXP.Value = SXP.Value - Strength.Value * 100
        Strength.Value = Strength.Value + 1
        end
end)

Strength.Changed:Connect(function()
        local uniquekey = 'id'..plr.userId
    local Savevtable = {plr.sub.Strength.Value}
    DSService:SetAsync(uniquekey,Savevtable)
end)
]]
end)


game.Players.PlayerRemoving:Connect(function(plr)
    local uniquekey = 'id'..plr.userId
    local Savevtable = {plr.sub.Strength.Value}
    DSService:SetAsync(uniquekey,Savevtable)
end)
