"attempt to index a number value" DataStore?

game.Players.PlayerAdded:connect(function(Player)

    local gameData;

    local CanSave=Instance.new('BoolValue',Player)

    end)

    if DataFetchSuccess then 

        if PlayerData~=nil then 
            PlayerData:Clone().Parent = Player
        else 
            Player.plrData.Credits.Value=100    
        end

    else 


        Player.CanSaveData.Value=false
        Player:Kick("[SERVER] DS002 (Check the Manual for more information.)")  

    end

end)
game.Players.PlayerRemoving:connect(function(Player)

    if Player.CanSaveData.Value==false then return end 

    local PlayerData=Player.plrData

    local DataWriteSuccess,ErrorMessage=pcall(function() 
        DataStore:SetAsync(tostring(Player.UserId),PlayerData)
    end)    

    if not DataWriteSuccess then 

        local Retry_Count=0

        while Retry_Count<6 do
            wait(60) 
            local Succeded,Error=pcall(function()
                DataStore:SetAsync(tostring(Player.UserId),PlayerData)
            end)
            if Succeded then break end 
            Retry_Count=Retry_Count+1
        end

    end

end)

On Line 31, it gives me the title error. How could I clone the player's data if they played already?
