[CLOSED]Why isn't the value that the script is in slowly decreasing?

I have it so the value that the script is in will go down 1 ever 2 seconds, and it worked outside of the player but as soon as i made it go inside of the player as a leaderstat, it doesnt work.

repeat
print("going")
	script.Parent.Value = script.Parent.Value - 1
wait(0.5)
print("gone")
until 9 + 10 == 21

I have fixed the problem, instead of making the script go inside of the value, i made it edit it instead! here is the finished and working script!

repeat
print("going")
	script.Parent.Parent.Parent.Air.Oxygen.Value = script.Parent.Parent.Parent.Air.Oxygen.Value - 1
wait(2.5)
print("gone")
until 9 + 10 == 21

Thank you!!!

1: Are you aiming for an infinite loop? because 9 + 10 will never equal 21, if that is the case, use a While loop instead while true do print("blah") wait() end, if not then your output will look like going gone going gone going gone ...etc.

And what do you mean by "i made it go inside of the player as a leaderstat"?

You should use a while loops or should say "i would"

local Number  = script.Parent
while wait(2) do	-- Waits two seconds and then does this.

	print("going")
	    Number.Value = Number.Value - 1 -- Subtracts number by 1
	wait(0.5)

	if Number.Value >= 21 then -- If Number is greater then 21 it will print "gone"
		print("gone")
	end
end

Hope this helped.
