Attempted to index nil with `Name`?

To start, My script is supposed to put a "(Name) joined the game" Message in the chat

I have a script a local script and a remote event for this,

In Replicatedstorage i have ReplicatedStorage.Events(a folder).Added(a remote event)

local events = game.ReplicatedStorage.Events
local Players = game:GetService("Players")

game.Players.PlayerAdded:Connect(function(plr)
    events.Added:FireAllClients()
end)

And my local script for putting the message in chat: (Located in startergui)

local events = game.ReplicatedStorage.Events
local starterGui = game.StarterGui
local Players = game:GetService("Players")

events.Added.OnClientEvent:Connect(function(plr)
    starterGui:SetCore("ChatMakeSystemMessage",{
        Text = plr.Name.." has arrived to the island";
        Color = Color3.fromRGB(255,0,0);
        Font = Enum.Font.Creepster;
        FontSize = Enum.FontSize.Size32;
    })
end)

My error message is : Players.Goblinc0re.PlayerGui.Message:7: attempt to index nil with Name (goblinc0re is my username)

If you could provide any help i would appreciate it
