Leaderstat gui not working after a player resets?

I made a Profile Gui which allows players to veiw their stats (Levels, Exp, Coins, etc,) and I made this script:

local cash = script.Parent.Parent.Parent.Parent.Parent.leaderstats:WaitForChild("Coins")

function changed()
	script.Parent.Text = "Coins: "..cash.Value
end

cash.Changed:connect(changed)

Everything worked fine in studio and in game. I tested it out with a couple of my friends and it was all working for them. But once we all reset the script no longer showed the stats. Is there something I did wrong? (The script above is for the Coins Stat.)
