Hello, im new here so here is a twiiter code script but how do i add another code because it underlines elseif Script:

-- variables
local player = game.Players.LocalPlayer
local event = game.ReplicatedStorage.Code
local code = player:FindFirstChild("Codes")
local codetable = {
	code1 = "Welcome",
	code2 = "Release",
}

-- optional code if you want your codes to expire after a time
local date = os.date("*t", os.time())

script.Parent.MouseButton1Click:Connect(function()
	if script.Parent.Parent.Parent.CodeHandle.Text ~= "code1" then
		-- example of a code that can expire
		if script.Parent.Parent.Parent.CodeHandle.Text == codetable.code1 then
			if date["month"] == 10 and date["day"] <= 10 and date["year"] == 2021 then
				-- doing this just to test the expiration of the code!!!
				if not code:FindFirstChild("Code1") then -- these two must be same
					event:FireServer("Code1", 100) -- cash reward
					script.Parent.Text = "Code Successfully Redeemed!"
					script.Parent.Parent.SuccessAudio.Playing = true
					script.Parent.Parent.CodeHandle.Text = ""
					wait(2)
					script.Parent.Text = "Redeem"
				else
					script.Parent.Text = "Already Readeemed"
					script.Parent.Parent.CodeHandle.Text = ""
					wait(2)
					script.Parent.Text = "Redeem"
				end
			else
				script.Parent.Text = "Code Expired!"
				script.Parent.Parent.ErrorAudio.Playing = true
				script.Parent.Parent.CodeHandle.Text = ""
				wait(2)
				script.Parent.Text = "Redeem"
			end
		elseif script.Parent.Parent.Parent.CodeHandle.Text == codetable.code2 then
			if not code:FindFirstChild("Code2") then
				event:FireServer("Code2", 100)
				script.Parent.Text = "Code Successfully Redeemed!"
				script.Parent.Visible = false
				script.Parent.Parent.Redeem2 = true
				script.Parent.Parent.SuccessAudio.Playing = true
				script.Parent.Parent.CodeHandle.Text = ""
				wait(2)
				script.Parent.Text = "Redeem"
			else
				script.Parent.Text = "Already Redeemed"
				script.Parent.Parent.CodeHandle.Text = ""
				wait(2)
				script.Parent.Text = "Redeem"
			end
		else
			script.Parent.Text = "Invalid Code"
			script.Parent.Parent.ErrorAudio.Playing = true
			wait(2)
			script.Parent.Text = "Redeem"
		end

		script.Parent.Text = "Enter Code"
		wait(2)
