Walk speed and jump power change doesn't apply on respawn?

Closed since I got help from another person, still appreciated.

Here is the script:

local TweenService = game:GetService("TweenService")

local sounds = game.Workspace.Sounds
local player = game.Players.LocalPlayer

local tweenInfo = TweenInfo.new(0.2,Enum.EasingStyle.Linear)
local SongFadeTweenInfo = TweenInfo.new(0.5,Enum.EasingStyle.Quad)
local SongFadeOut = TweenService:Create(sounds.MainMenu,SongFadeTweenInfo,{Volume=0})

local button = script.Parent.Parent:WaitForChild("PlayButton")

function set_speed(character, walkspeed, jumppower)
  local humanoid = character:WaitForChild("Humanoid")
  humanoid.WalkSpeed = walkspeed
  humanoid.JumpPower = jumppower
end

button.MouseEnter:Connect(function()
    button.Parent.Texty.Visible = true
end)

button.MouseLeave:Connect(function()
    button.Parent.Texty.Visible = false
end)

button.MouseButton1Click:Connect(function()
    local Character = game.Workspace:FindFirstChild(player.Name)
    player.CharacterAdded:Connect(function(char) set_speed(char, 16, 50) end)
    script.Parent.Visible = false
    script.Parent.Parent.Texty.Visible = false
    SongFadeOut:Play()
    wait(2)
    script.Parent.Parent.ImageLabel.Visible = false
    script.Parent.Parent.TextLabel.Visible = false
    game.Lighting.Blur:Destroy()

    set_speed(Character, 16, 50)

    wait(5)
    script.Parent.Parent.ModeSelectFrame.Visible = true
    script.Parent.Parent.ModeSelectBackground.Visible = true
    script.Parent.Parent.Texty2.Visible = true
end)

Don't know how to mark my answer as a solution, but do know that I have the script fixed.

A solution to this answer would to make a datastore for your walk and jump. Here is an example of a walkspeed datastore:

local DataStore = game:GetService("DataStoreService"):GetDataStore("SpeedData")

game.Players.PlayerAdded:Connect(function(Player)
    local speedData = DataStore:GetAsync("WalkSpeed-"..Player.UserId)
    local SpeedValue = Instance.new("IntValue",Player)
    SpeedValue.Name = "PlayerSpeed"



    local success,error = pcall(function()
        SpeedValue.Value = speedData
    end)
    if error then
        SpeedValue.Value = 16
    end

    Player.CharacterAdded:Connect(function(Char)
        local hum = Char:WaitForChild("Humanoid")
        if hum then
            hum.WalkSpeed = SpeedValue.Value
            SpeedValue.Changed:Connect(function()
                hum.WalkSpeed = SpeedValue.Value
            end)
        end

    end)
end)

game.Players.PlayerRemoving:Connect(function(Player)
    local success,error = pcall(function()
        DataStore:SetAsync("WalkSpeed-"..Player.UserId,Player.PlayerSpeed.Value)
    end)
    if not success then
        warn(error)
    else
        print(success)
    end
end)

This is just an example I found on the internet try making your own if you can this one may or may not work and you will probably need to set it up with your system Resource Hope this helps!!
