not working

You can't get the ui from StarterGui

Only from PlayerGui which is located within the Player

[twin heron]

StarterGui puts it into PlayerGui once the player loads

You can use game:GetService("Players"):FindFirstChild("(PlayerName)").PlayerGui

And them whatever ui you want to access

Then*

Oh mb

You can either put the script within StarterPlayerScripts and locate the gui from there

Or put them inside the ScreenGui

[runic rune]

This is the easier option

[runic rune]

Nope

The game clones EVERYTHING within StarterGui and put's it in a custom folder called PlayerGui. This gives each player their own seperate ui

local Player = game:GetService("Players").LocalPlayer
local PlayerGui = Player:WaitForChild("PlayerGui") --We use `WaitForChild` to stop the script and wait until it exists
