Workspace.TeleporterOutShop .ProximityPrompt.Script:12: attempt to index nil with 'PlayerGui'

Hi,
I don’t know what to do it says attempt to index nil with ‘PlayerGui’ here is the script:

script.Parent.Triggered:Connect(function(player)
	local Cheeseburger = player:WaitForChild("Backpack"):FindFirstChild("Cheeseburger")
	if Cheeseburger then
		local Rage = player.PlayerGui.Rage
		Rage.Enabled = true
	end
end)

any help is appreciated

try adding :WaitForChild() for PlayerGui it should not make any since for your script not to work tho
