Is this DataStore request written properly? [closed]

local Lvl=p.leaderstats.Lvl--P is a player
local Get=Game:GetService("DataStoreService"):GetDataStore("Points"):GetASync(p.Name.."Lvl")
if Get then
    Lvl.Value=Get
elseif not Get then
    Game:GetService("DataStoreService"):GetDataStore("Points"):SetASync(p.Name.."Lvl", 1)
    Lvl.Value=1
end

Thank you for your time. I'm afraid if I test it I might mess something up, seeing as it saves...

EDIT: Here's the full script. I'd be very grateful if you could read it and let me know if you see any obvious errors.

while not script.Parent.Parent.Parent.Parent.leaderstats.Lvl do wait() end

local p=script.Parent.Parent.Parent.Parent
local Lvl=p.leaderstats.Lvl
local Exp=Instance.new("IntValue")
Exp.Parent=script.Parent
Exp.Value=0

local Get=Game:GetService("DataStoreService"):GetDataStore("Points"):GetAsync(p.Name.."Lvl")
if Get then
    Lvl.Value=Get
elseif not Get then
    Game:GetService("DataStoreService"):GetDataStore("Points"):SetAsync(p.Name.."Lvl", 1)
    Lvl.Value=1
end

local Goals={50, 100, 250, 500, 750, 1000, 2500, 5000, 10000}
function Raise()
    for i, v in ipairs(Goals) do
        if Exp.Value==v then
            Game:GetService("DataStoreService"):GetDataStore("Points"):IncrementAsync(p.Name.."Lvl")
            Lvl.Value=i
            script.Parent.Bar.Size=Udim2.new(0, 0, 0, 20)
            Exp.Value=0
        end
    end
    if Exp.Value~=0 then
    script.Parent.Bar.Size=Udim2.new(0, 140/Exp.Value, 0, 20)
    end
end

while true do
wait(3)
Exp.Value=Exp.Value+1
Raise()
end
