How do I fix this problem?

I am trying to do mainly 3 things 1. Award a badge to the player if he/she does not have it 2. Give the player a random number 1-4 3. Save that number I think the mistake is obvious since it is my first time using the DataStoreService, anyways, the mistake is that when I try to print the value, what comes out is nil

game.Players.PlayerAdded:connect(function(Player)
local Badge=game:GetService("BadgeService")
local ID=Player.userId
local ID=(tostring(ID))
    if not Badge:UserHasBadge(ID,208585099) then
    Badge:AwardBadge(ID,208585099)
    local DataStore= game:GetService("DataStoreService"):GetDataStore(Player.Name)
    local Random=math.random(1,4)
    print(Random)
    DataStore:SetAsync(Player,Random) 
    print(DataStore:GetAsync(Player))
    else 
    local DataStore= game:GetService("DataStoreService"):GetDataStore(Player.Name)
    local RealRandom=DataStore:GetAsync(ID)
    print(RealRandom)
    end
end)
