:GetPropertyChangedSignal() Not detecting Change in Value?

Im having this weird issue. Basically when the PlayerCount goes up when you enter a lobby and I have a script here to start a timer if the playercount > 3 but the script never detects the GetPropertyChangesSignal().

script.Parent.Parent.Players:GetPropertyChangedSignal("Value"):Connect(function()
	if script.Parent.Players.Value >= 3 then
		if script.Parent.Value == 0 then
			script.Parent.Value = 30
		end
	end
	if script.Parent.Players.Value < 3 then
		script.Parent.Value = 0
	end
end)

Same with the other script I have that does the timer.

script.Parent:GetPropertyChangedSignal("Value"):Connect(function()
	if script.Parent.Value ~= 0 then
		wait(1)
		script.Parent.Value = script.Parent.Value - 1
	end
end)

I also tested printing right after the value change was detected and it would never print anything for both scripts.

The weird this is that in the PlayerGUI scripts it detects them just fine
