Attempt to index nil leaderstats?

hey there so I'm making a game and a sell area for points ok? so when i touch the brick my script is:

script.Parent.Touched:Connect(function() if game.Players.LocalPlayer.leaderstats.Potatoes.Value == 6 then game.Players.LocalPlayer.leaderstats.Cash.Value = game.Players.LocalPlayer.leaderstats.Cash.Value +10 end end)

and it get this error:Attempt to index nil with leaderstats

First, make this a server script, it won't work if it's a local script. (I also did getplayerfromcharacter because you cant get a localplayer from a server script.)

Second, use waitforchild just in case the leaderstats hasn't loaded yet!

edited code:

script.Parent.Touched:Connect(
    function(hit)
        local Player = game.Players.GetPlayerFromCharacter(hit.Parent)
        if Player:WaitForChild("leaderstats"):WaitForChild("Potatoes").Value == 6 then
            Player.leaderstats.Cash.Value = Player.leaderstats.Cash.Value + 10
        end
    end
)

Accept answer if it works.
