I dont get an error or anything so idk what isnt working
script.Parent.TextBox.Text = script.Parent.Parent.Parent.Character.Humanoid.WalkSpeed
Ur not locating the Player you're locating nothing as ur telling ur script to find Character in ScreenGui which isn't valid instead do
lua
game:GetService('Players').LocalPlayer.Character.Humanoid.Walkspeed
Also this will not work at all (Meaning this script will not work at all if this is a server sided script)
Also edit for the entire line
```lua
script.Parent.TextBox.Text = game:GetService('Players').LocalPlayer.Character.Humanoid.Walkspeed
