What is wrong with this function?

So i'm trying to get my chat script to say when I join the game but it's not working. The console doesn't show any errors, but when I join, it doesn't say the message I want it to in my chat.

local Players               = game:GetService("Players")
local GroupId = 1233617

game.Players.PlayerAdded:connect(function(plr)
    local Rank = plr:GetRankInGroup(GroupId)
    local Role = plr:GetRoleInGroup(GroupId)

if Rank == 255 then
    local player = Players:FindFirstChild(plr.Name)
        if plr.Name == "centerspell" then
            _G.sysMsg("The Owner "..plr.Name.." has joined the server!", "Royal Purple")
        end
    end
end)

This defines the function in a different script.

function _G.sysMsg(msg,type)
    local title = ""
    local def=BrickColor.new(type)
    local v=Instance.new("StringValue")
    v.Name = "Message"
    v.Value=msg
    local col=Instance.new("Color3Value",v)
    col.Name="Color"
    col.Value=def.Color
    game.Debris:AddItem(v,3)

    local gui=game.StarterGui["ChatGUI"].Chat
    local t1=gui.Text1
    local t2=gui.Text2
    local t3=gui.Text3
    local t4=gui.Text4
    local t5=gui.Text5
    local t6=gui.Text6
    local t7=gui.Text7
    local t8=gui.Text8
    local t9=gui.Text9

    t1.TextColor3=t2.TextColor3
    t1.Text=t2.Text
    t2.TextColor3=t3.TextColor3
    t2.Text=t3.Text
    t3.TextColor3=t4.TextColor3
    t3.Text=t4.Text
    t4.TextColor3=t5.TextColor3
    t4.Text=t5.Text
    t5.TextColor3=t6.TextColor3
    t5.Text=t6.Text
    t6.TextColor3=t7.TextColor3
    t6.Text=t7.Text
    t7.TextColor3=t8.TextColor3
    t7.Text=t8.Text
    t8.TextColor3=t9.TextColor3
    t8.Text=t9.Text
    t9.TextColor3=col.Value
    t9.Text=v.Value

    v.Parent=workspace.ChatRecorder
end
