How do i link leaderstat speed?

how do i link the speed value in the leaderstat to the local player walkspeed

    local dataStores = game:GetService("DataStoreService"):GetDataStore("Speed")

local deafaultSpeed = 0

local playerLeft = 0

  

game.Players.PlayerAdded:Connect(function(player)

local PlayerGui = player:WaitForChild('PlayerGui')

playerLeft = playerLeft + 1

local leaderstats = Instance.new("Folder")

leaderstats.Name = "leaderstats"

leaderstats.Parent = player

wait(1)

local speed = Instance.new("IntValue")

speed.Name = "Speed"

speed.Value = game.StarterGui.ScreenGui.speed.Text

speed.Parent = leaderstats

Try this out mate

function onChanged()
player.Character:WaitForChild("Humanoid").WalkSpeed = speed
end
speed.Changed:Connect(onChanged)

The onChanged function sets the walkspeed to the speed value and the function fires every time speed has changed so it updates whenever you change the speed value. Hope this helps mate
