Why won't an elseif statement i wrote run after i die in game?

Hi hello. it's me again, the dude that has the worst scripts on this entire website

So, with the help of a user named blowup999 (go check them out), i have fixed my battle script

However another problem arose.

--Variables

local parts = game.Workspace.Parts:GetChildren()
local Players = game:GetService("Players")
local Dummy = game.Workspace.Dummy
local DummyHumanoid = Dummy.Humanoid
local debounce = false
local player = Players.LocalPlayer
local Character = player.Character
local Humanoid = Character:WaitForChild("Humanoid")
local FadeInFrame = script.Parent.Parent.FadeInUI.FadeInFrame

--Battle Loop

for i, v in pairs(parts) do
    v.Touched:Connect(function(hit)
        if hit.Parent:FindFirstChild("Humanoid") then

            script.Parent.Parent.FadeInUI.Enabled = true

            FadeInFrame.BackgroundTransparency = 1

            for k = 1,100 do
                FadeInFrame.BackgroundTransparency -= 0.01
                wait(0.05)
                if FadeInFrame.BackgroundTransparency == 0 then
                    break
                end
            end
            script.Parent.Parent.FadeInUI.Enabled = false

            Humanoid.WalkSpeed = 0
            Humanoid.JumpPower = 0
            script.Parent.Enabled = true
            Character:FindFirstChild("HumanoidRootPart").CFrame = game.Workspace.TpPart.CFrame + Vector3.new(0,1,0)

            if script.Parent.Enabled == true then
                if script.Parent.AtkSelector.Punch.MouseButton1Click then
                    script.Parent.AtkSelector.Punch.MouseButton1Click:Connect(function()
                        if not debounce then
                            debounce = true
                            DummyHumanoid.Health = DummyHumanoid.Health - 50

                            local function typeText(text)
                                for i = 1, #text do
                                    script.Parent.DialogueLabel.Text = string.sub(text, 1, i)
                                    wait()
                                end
                                wait(1.5)
                                script.Parent.DialogueLabel.Text = ""
                            end

                            if DummyHumanoid.Health <= 0 then
                                typeText("You won!")
                                Humanoid.WalkSpeed = 16
                                Humanoid.JumpPower = 40
                                script.Parent.AtkSelector.Punch.Visible = false
                                script.Parent.AtkSelector.Kick.Visible = false
                                script.Parent.AtkSelector.Cancel.Visible = false
                                script.Parent.Enabled = false
                                DummyHumanoid.Health = 100
                                debounce = false
                                v:Destroy()
                            else
                                script.Parent.AtkSelector.Visible = false
                                script.Parent.MagicSelector.Visible = false
                                wait(1)                 

                                typeText("This is the core battle system")
                                typeText("Isn't this cool???")                  
                                typeText("No??")
                                typeText("Welp, I tried")
                                Humanoid.Health = Humanoid.Health - 100         
                                wait(1)
                                script.Parent.AtkSelector.Visible = true
                                script.Parent.MagicSelector.Visible = true
                                debounce = false
                            end
                        end 
                    end)            
                end     
            end 
        end
    end)
end

So, this is the entire script, i know its ugly and inefficient but hear me out on this one

So in this part

if DummyHumanoid.Health <= 0 then
    typeText("You won!")
    Humanoid.WalkSpeed = 16
    Humanoid.JumpPower = 40
    script.Parent.AtkSelector.Punch.Visible = false
    script.Parent.AtkSelector.Kick.Visible = false
    script.Parent.AtkSelector.Cancel.Visible = false
    script.Parent.Enabled = false
    DummyHumanoid.Health = 100
    debounce = false
    v:Destroy()
else
    script.Parent.AtkSelector.Visible = false
    script.Parent.MagicSelector.Visible = false
    wait(1)                 

    typeText("This is the core battle system")
    typeText("Isn't this cool???")                  
    typeText("No??")
    typeText("Welp, I tried")
    Humanoid.Health = Humanoid.Health - 100         
    wait(1)
    script.Parent.AtkSelector.Visible = true
    script.Parent.MagicSelector.Visible = true
    debounce = false

Something is missing here. If you can't guess what it is, im just gonna tell you.

I did not conclude the possibility that the player can die, so, even if the player dies, this will go on forever.

I thought adding an elseif statement after the first if was gonna work

Something along the lines of this

if DummyHumanoid.Health <= 0 then
    typeText("You won!")
    Humanoid.WalkSpeed = 16
    Humanoid.JumpPower = 40
    script.Parent.AtkSelector.Punch.Visible = false
    script.Parent.AtkSelector.Kick.Visible = false
    script.Parent.AtkSelector.Cancel.Visible = false
    script.Parent.Enabled = false
    DummyHumanoid.Health = 100
    debounce = false
    v:Destroy()
elseif Humanoid.Health <= 0 then
    typeText("Ded")
    Humanoid.WalkSpeed = 16
    Humanoid.JumpPower = 40
    script.Parent.AtkSelector.Punch.Visible = false
    script.Parent.AtkSelector.Kick.Visible = false
    script.Parent.AtkSelector.Cancel.Visible = false
    script.Parent.Enabled = false
    DummyHumanoid.Health = 100
    debounce = false
else
    script.Parent.AtkSelector.Visible = false
    script.Parent.MagicSelector.Visible = false
    wait(1)                 

    typeText("This is the core battle system")
    typeText("Isn't this cool???")                  
    typeText("No??")
    typeText("Welp, I tried")
    Humanoid.Health = Humanoid.Health - 100         
    wait(1)
    script.Parent.AtkSelector.Visible = true
    script.Parent.MagicSelector.Visible = true
    debounce = false
end

Apparently, it doesn't, the battle UI stays visible after i die and the dummy does not get healed, nor the typeText() function runs.

I might be missing something obvious here, but i still need some help.

I'd appreciate any help you all can give. Thank you
