My Custom Chat won't paste my Chat-text?

I got this Code from Wiki, And I changed it to the way I want it, like Fade, Tweening, and Colors, but I don't want ROBLOX's Default Chat Bar, I wanna make my own, But it won't respond back, here is the code :

local Teams = script.Teams

local t1 = Teams.Team1
local t2 = Teams.Team2

wait(.1)

function UpdateOldLabels(Parent)
    for i,v in pairs(Parent:GetChildren()) do
        if v.Name:sub(1,4):lower() == "line" then
            local LineNumber = v.Name:sub(5)
            if LineNumber == "12" then
                v:Destroy()
            else
                v.Name = "line"..tostring(tonumber(LineNumber) + 1)
                v.Position = v.Position - UDim2.new(0,0,0,20)
            end
        end
    end
end
print'l11'
game:GetService("Players").PlayerAdded:connect(function(player)
        for _,v in ipairs(game:GetService("Players"):GetChildren()) do
            v.PlayerGui.Chat.TextBox.FocusLost:connect(function()
            UpdateOldLabels(v:WaitForChild("PlayerGui").Chat.chatframe)
            print'lol'
            newchatline = Instance.new("TextLabel",v:WaitForChild("PlayerGui").Chat.chatframe)
            newchatline.Text = player.Name.. ": " ..v:WaitForChild("PlayerGui").Chat.TextBox.Text
            newchatline.Size = UDim2.new(1,0,0,20)
            newchatline.Position = UDim2.new(0,0,1,-1)
            newchatline.Font = "SourceSansBold"
            newchatline.TextColor3 = Color3.new(255,255,255)
            newchatline.TextStrokeTransparency = 0
            newchatline.BackgroundTransparency = 1
            newchatline.TextTransparency = 1
            newchatline.BorderSizePixel = 0
            newchatline.FontSize = "Size18"
            newchatline.TextXAlignment = "Left"
            newchatline.TextYAlignment = "Top"
            newchatline.ClipsDescendants = true
            newchatline.Name = "line1"
        end)
        UpdateOldLabels(game:GetService("StarterGui").Chat.chatframe)
        newchatline:Clone().Parent = game:GetService("StarterGui").Chat.chatframe
        for _,plr in next, game.Players:GetChildren() do
            if plr.TeamColor == t1.Value then
                newchatline.TextStrokeColor3 = t1.Value.Color
                for i = 1,0,-.1 do
                    wait()
                    newchatline.TextTransparency = i
                    newchatline:TweenPosition(UDim2.new(0,0,1,-15),"Out", "Quad", .1, true)
                    end
                end
            end
        end
end)
