Why doesn't the GUI Appear after the Player Joins?

Hello guys,

So I would like when a player joins with 69 Active Multipliers, a GUI goes visible. I have also tried Debugging the code as you can see, but it only prints yes and nothing happens after that, the GUI doesn't turn visible.

My script:

game.Players.PlayerAdded:Connect(function(player)
    wait(.5)
    if player:WaitForChild("Other Stats"):WaitForChild("Active Multipliers").Value == 69 then
            player:WaitForChild("PlayerGui"):WaitForChild("TimerMultipliersGui"):WaitForChild("TimerMultiplierFrame").Visible = true
        print("GUI Turned Visible.")
    else
        print("You do not have 69 Active Multipliers!")
    end
end)

Here is where the GUI is located at: https://ibb.co/FqM0jvX (It's a picture and I can't post pictures here so I posted it on an Image Hosting Website.

Thank you.
