How do you make a fade-in frame when play button pressed?

I'm making a playbutton that's gonna teleport you to another place when pressed. I want a smooth trasition to my upcoming loading screen that I'm gonna make later so I would appreciate some help to get this headache out of the way.

NOTE: The scripts that have anything to do with sounds work.

I've tried multiple ways and none have worked yet.

The code:

local BlackFading = game.StarterGui.LoadingScreen.FirstBlack

PlayButton.MouseButton1Down:Connect(function() game.StarterGui.PlayMenu.OnlineClicked.Value = true script.Parent.OnlineClick:Play() script.Parent.ImageColor3 = Color3.new(0, 1, 0) wait(1) script.Parent.ImageColor3 = Color3.new(255,255,02550) wait(0.1) wait(3)

-- Everything above this works --

for i = 1,100 do
    BlackFading.BackgroundTransparency -= 1 -- First of black screen,
    wait(0.01)
end
wait(3)
BlackFading.Parent.DramaticHit:Play()  -- A dramatic hit sound plays (works)
wait()
for i = 1,100 do
    BlackFading.ImageLabel.ImageTransparency -= 1 -- my group icon appears
    wait(0.01)
end
for x = 1, 0, -0.1 do
    workspace.SOUNDS.GARAGE.Volume = x -- background music fades away(works)
    wait(0.01)
end
for i = 1,100 do
    BlackFading.TextLabel.TextTransparency -= 1 -- a text below the icon appears
    wait(0.01)
end

end)
