Why is the boolean niling in the local player?

local groupId = 5144614
local Admin = game.Players.LocalPlayer.importantplr.Admin

function added(player)


if game.Players.LocalPlayer:GetRankInGroup(groupId) <= 16 then
		game.Players.LocalPlayer:WaitForChild("importantplr")
		game.Players.LocalPlayer.importantplr:WaitForChild("Admin")
		Admin.Value = true
	else
		Admin.Value = false
end

end

game.Players.PlayerAdded:connect(added)

Its purpose is to change a value known as admin, which is a boolean that is used so my scripts can read it and then decide if the player should see somethings or not. It keeps niling. I dont understand why, thanks for the help.

I'd write your code like this...

I changed the function format(does the same thing) also changed your "local player" to player since the playeradded function will give you the player

local groupId = 5144614

game.Players.PlayerAdded:Connect(function(player)
	local Admin = player:WaitForChild(importantplr).Admin
	if player:GetRankInGroup(groupId) <= 16 then
		Admin.Value = true
	else
		Admin.Value = false
	end 
end)
