How do i make another code like from simulators because it underlines elseif? [closed]

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!"

                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 = ""
