Why does this work in studio but not in game? [Filtering Enabled]

I made this scanner script that'll set an alarm off if you're not in the group, but it does it for everyone. Please help!

Disabler.MouseClick:Connect(function()
	Alarm:Stop()
	print("Alarm on")
	Light1.BrickColor = BrickColor.new("Dark green")
			Light2.BrickColor = BrickColor.new("Dark green")
			Light3.BrickColor = BrickColor.new("Dark green")
			wait(.001)
		Light1.BrickColor = BrickColor.new("Bright red")
			Light2.BrickColor = BrickColor.new("Bright red")
			Light3.BrickColor = BrickColor.new("Bright red")
			Alarm:Play()
			wait(26)
			Light1.BrickColor = BrickColor.new("Dark green")
			Light2.BrickColor = BrickColor.new("Dark green")
			Light3.BrickColor = BrickColor.new("Dark green")
			Alarm:Stop()
			print("Alarm off")
	end)
Scanner.Touched:Connect(function(Player)
	if debounce == false then
		debounce = true
		Scan:Play()
		Scanner.Transparency = .8
		wait(.6)
		Scanner.Transparency = .9
		if Rank <= 1 then
			print("Alarm on")
			Alarm:Stop()
			Light1.BrickColor = BrickColor.new("Dark green")
			Light2.BrickColor = BrickColor.new("Dark green")
			Light3.BrickColor = BrickColor.new("Dark green")
			wait(.001)
			Light1.BrickColor = BrickColor.new("Bright red")
			Light2.BrickColor = BrickColor.new("Bright red")
			Light3.BrickColor = BrickColor.new("Bright red")
			Alarm:Play()
			wait(26)
			Light1.BrickColor = BrickColor.new("Dark green")
			Light2.BrickColor = BrickColor.new("Dark green")
			Light3.BrickColor = BrickColor.new("Dark green")
			Alarm:Stop()
			print("Alarm off")
			end
			debounce = false
	end
end)
end)

Thanks if you can help

Use player:IsInGroup() instead of rank

local groupId = 0 --group id
if plr:IsInGroup(groupId) then

else
	print("Alarm on!")
end
