[Solved] Why is the collectable coin not working?

I was trying to make a collectable ring, everything was working. Once I collect the ring, it turns invisible. However the ring is not turning opaque again even though I have wrote the script to turn it's transparency to 0.

There are no errors in the output either

Here is the code:

local db = true
script.Parent.Touched:Connect(function(hit) -- The player hits the part
	if hit.Parent:FindFirstChild("Humanoid") ~= nil then -- Just to check if its not nil
		if db == true then -- Just to check if the db is true
			db = false
			local player = game.Players:GetPlayerFromCharacter(hit.Parent) -- Getting the player
			player.leaderstats.Rings.Value = player.leaderstats.Rings.Value + 1 -- Giving Currency
			script.Parent.Transparency = 1 -- Making it invisible
			script.Parent.CanCollide = false -- Now the player can walk through the ring
			script.Parent.Bubble:Play() -- Playing the sound
			wait(2)
-- Respawning the ring:
			db = true 
			script.Parent.Transparency = 0
			script.Parent.CanCollide = true
		end
	end
end)

Anything I can do?

The script works fine for me, It's either 1: Your sound is probably misspelled or something. 2: You do not have leader stats or the leader stats is misspelled again.
