Is there a way to fix the problem of the script subtracting 1 when the IntValue hits to 0?

Hello to the person reading this. My script is refusing to stop subtracting a number when it hits 0.

Here is the script

local Inter = Instance.new("IntValue") -- Creates the Value
Inter.Parent = game.Workspace
Inter.Name = ("Intermission")
Inter.Value = 10

while true do
    repeat
        wait(1)
        Inter.Value = Inter.Value -1
        
    until Inter.Value == 0
end

@Uroxus's answer is the correct way to do it.

Below works but isn't correct.

local Inter = Instance.new("NumberValue") -- Creates the Value
Inter.Parent = game.Workspace
Inter.Name = ("Intermission")
Inter.Value = 10

repeat
	if Inter.Value ~= 0 then
		wait(1)
		Inter.Value = Inter.Value -1
	end
until Inter.Value == 0

A repeat loop checks its condition last, meaning it will always run the code inside at least once. I'm not sure what you're trying to do, but this would fix that problem:

local Inter = Instance.new("IntValue") -- Creates the Value
Inter.Parent = game.Workspace
Inter.Name = ("Intermission")
Inter.Value = 10

while true do
	while Inter.Value ~= 0 do
		wait(1)
		Inter.Value = Inter.Value -1
	end
	wait()
end

However this is bad code. Instead a simple for loop would do:

local Inter = Instance.new("IntValue") -- Creates the Value
Inter.Parent = game.Workspace
Inter.Name = ("Intermission")
Inter.Value = 10

for i = Inter.Value, 0, -1 do
	wait(1)
	Inter.Value = i
end

If this isn't what you wanted please explain in greater detail what you want the code to do.

local Inter = Instance.new("IntValue") -- Creates the Value

Inter.Parent = game.Workspace

Inter.Name = ("Intermission")

Inter.Value = 10

    repeat
        wait(1)
        Inter.Value = Inter.Value -1
    until Inter.Value == 0

Its an infinite loop. The while true do part kept repeating the repeat wait(1) until part.
