eaderstats script works in Studio, but not Roblox game, why? (is this specific enough)

This script is supposed to take the value of Views, divide it by 35, and have the quotient be the value of Subscribers. It works in Studio but not in my game. I have tried many things: using WaitForChild, not using anything, putting a wait period of 5 minutes at the beginning of the script (what you see here) lots of different things. This is the script:

wait(300)
dividedby = 35
while true do
	wait(1)
	for _,player in pairs(game.Players:GetPlayers()) do
if player:FindFirstChild("leaderstats")then
	player.leaderstats.Subscribers.Value = ( player.leaderstats.Views.Value / dividedby )
end
end
end

use player:WaitForChild("leaderstats")~=nil then
