help giving a player an effect if they have a pass?

local player = script.Parent.Parent
local sparklesPass = 194931606
local firePass = 194930756

function sparklesisAuthenticated(player)
    return game:GetService("GamePassService"):PlayerHasPass(player, sparklesPass)
end

function fireisAuthenticated(player)
    return game:GetService("GamePassService"):PlayerHasPass(player, firePass)
end

while wait() do
	if sparklesisAuthenticated(player) then
		local torso = player:FindFirstChild("Torso")
		if torso then
			local sparkles = Instance.new("Sparkles", torso)
			sparkles.SparkleColor = Color3.new(1, 1, 1)
		end
	end
	if fireisAuthenticated(player) then
		local torso = player:FindFirstChild("Torso")
		if torso then
			local fire = Instance.new("Fire", torso)
			fire.Color = Color3.new(0, 170/255, 1)
			fire.SecondaryColor = Color3.new(0, 0, 0)
			fire.Heat = 25
			fire.Size = 10
		end
	end
end

This script is inside StarterPack, and I want to give the player an effect if they have the passes, I don't know why it doen't work.
