I have a question and i need Help!?

I have now spent a very long time writing a script that says that if you equip this tool then in the StarterGui the visibility of an object named there in the script is set to true or false:

if script.Parent.Equipped:Connect() then
	game.StarterGui.Objectives.Frame.Framel.Objective1.Visible = false
	game.StarterGui.Objectives.Frame.Framel.Objective2.Visible = true
end

(This is a localscript in the tool)

But that never works there comes then always something with a nil value and there I wanted to ask if someone has a better script or a better idea to fix this problem.

use

if script.Parent.Equipped:Connect() then
    game.Players.LocalPlayer.PlayerGui.Objectives.Frame.Framel.Objective1.Visible = false
    game.Players.LocalPlayer.PlayerGui.Objectives.Frame.Framel.Objective2.Visible = true
end

because startergui effects the gui at the starting point, that's why it's named startergui. but for the player, it has it's own separate gui folder it uses

local tool = script.Parent
game.Players.PlayerAdded:Connect(function(Player)
	local PlayerGui = Player:WaitForChild("PlayerGui")
	local Objectives = PlayerGui:WaitForChild("Objectives")
	local Frame = Objectives:WaitForChild("Frame")
	local Frame1 = Frame:WaitForChild("Frame1")
	local Objective1 = Frame1:WaitForChild("Objective1")
	local Objective2 = Frame1:WaitForChild("Objective2")
	tool.Equipped:Connect(function()
		Objective1.Visible = false
		Objective2.Visible = true
	end)
end)

I haven't tested this out yet, but try it.
