Why is this script that is suposed to continuously update a leaderstat not working?

This script is supposed to continuously update a player's Ratio value based on their kills and deaths.

However, the script doesn't work, and output gave me nothing.

Can someone please help me?

Here's the script:

local Player = game.Players.LocalPlayer
local stats = Player:WaitForChild("leaderstats")

while wait(0.1) do
    if Player ~= nil then
        if stats ~= nil then
            stats.Ratio.Value = (stats.Kills.Value/math.max(1,stats.Deaths.Value))
        end
    end
end
