why won't my function connect and text appear?

I've created a script that, upon click of "ClickyClick", makes a TextLabel gradually increase its transparency and all of my prints work except the text doesn't appear

function ChangeOfMoneyGui(clicker)
	db = 0
	print("function connected")
	if db == 0 then
		db = 1
		print("debounce active")
		local plrg = clicker:FindFirstChild("PlayerGui")
		local mc = plrg.ChangeOfMoney.MoneyChangeFrame.MoneyChange
		local tt = mc.TextTransparency
		local st = mc.TextStrokeTransparency
		visible = false
		if visible == false then
			print("visible = true")
			visible = true
			appear(tt)
			appear(st)
			wait(2)
			disappear(tt)
			disappear(st)
			visible = false
		end
	end
end

game.Workspace.ClickyClick.ClickDetector.MouseClick:connect(ChangeOfMoneyGui)


function appear(transparency)
	print("appear function called")
	for i = 1, 0, .05 do
	transparency = i
	end
end	


function disappear(transparency)
	print("disappear function called")
	for i = 0, 1, .05 do
	transparency = i
	end
end

You get the Value of the Transparency and not set it to the new value and you did this loop:

for i = 1, 0, .05 do

this will not decrease i so it gets visible again you need to do the loop like this:

for i = 1, 0, -.05 do

try this :

function appear(object)
	print("appearing")
	for i = 1, 0, -.05 do
		object.TextTransparency = i
		object.Transparency = i
	end
end

function dissappear(object)
	print("dissappearing")
	for i = 0, 1, 0.5 do
		object.TextTransparency = i
		object.Transparency = i
	end
end

function ChangeOfMoneyGui(clicker)
	db = 0
	print("connected")
	if db == 0 then
		db = 1
		print("debounce")
		local plrgs = clicker:FindFirstChild("PlayerGui")
		local mc  = plrgs.ChangeOfMoney.MoneyChangeFrame.MoneyChange
		visible = false
		if visible == false then
			print("visible now")
			visible = true
			appear(mc)
			wait(2)
			dissappear(mc)
			visible = false
			
		end
	end
end
