[SOLVED] How to make a GUI frame shake based on Health?

So I have an HP bar and when the players health gets low it starts shaking.

I have this script in a local script in the GUI:

-- Vars up here

-- Changed function
hum.HealthChanged:Connect(function(Health) 
	local maxHealth = hum.MaxHealth
	local lowPercent = 0.15 * hum.MaxHealth
	local lowEnough = Health < lowPercent  -- when the player is below 15%
	
	if lowEnough then
		if healthFrame:FindFirstChild("ShakeScript") ~= nil then
			healthFrame:FindFirstChild("ShakeScript").Disabled = false
		end
	else
		if healthFrame:FindFirstChild("ShakeScript") ~= nil then
			healthFrame:FindFirstChild("ShakeScript").Disabled = true
		end
	end
end)

The scripts disable and re enable like they're supposed to but nothing happens.
