Infinite Yield Possible on WaitForChild("IsDrown")

[Alexander_XIII (AppleCiderAlex)]

I want to make an oxygen system.
It just won’t work. It’s supposed to make the meter go down when underwater, i already have the underwater part working, THIS WONT WORK THOUGH.

local IsDrown = script.Parent:WaitForChild("IsDrown")
local oxygen = script.Parent:WaitForChild("oxygen")
local plrgui = game:GetService('Players').LocalPlayer:WaitForChild('PlayerGui')

IsDrown.Changed:Connect(function()
	print("mhm")
	if IsDrown.Value == true then
		print("alr")
		repeat
			if IsDrown.Value == true then
				print("ohk")
				wait(1)
				oxygen.Value = oxygen.Value - 1
				plrgui.Oxygen.TextLabel.Text = "oxygen: ".. oxygen.Value
			end
		until oxygen.Value <= 0
	end
end)

HELP

@Alexander_XIII

script.Parent:WaitForChild("IsDrown")

It means it can’t find that value

[Alexander_XIII (AppleCiderAlex)]

No, I know, but like it is supposed to.

Show me the hierarchy of your script / values if you can

[Alexander_XIII (AppleCiderAlex)]

game, players, me(player), IsDrown.

@Alexander_XIII

IsDrown

I meant an image like this of how yours looks like

[Alexander_XIII (AppleCiderAlex)]

I’m going to be completely honest, I can’t find any screenshots on my PC, lol. I can’t find them after I take them

[Nitefal]

No problem does yours look like my first image or like this, with the value inside the script

[Alexander_XIII (AppleCiderAlex)]

No, the value is inside the player.

[Nitefal]

And your script is in the player as well or elsewhere?

[Alexander_XIII (AppleCiderAlex)]

I’m an idiot. The script is inside something inside the player. Thank you so much Nitefal. Hope you have a wonderful day.
