If you can answer this it would be really helpful if you included a script.
function playerAdded(plr)
local stats = Instance.new("IntValue", plr)
stats.Name = "leaderstats"
local money = Instance.new("IntValue", stats)
money.Name = "Jump Power"
money.Value = game.Players.plr.Character.Humanoid.JumpPower
end
game.Players.PlayerAdded:connect(playerAdded)

Nice answer, but you put connect on line 20, which is deprecated, I'm just reminding jalbraek to change connect to Connect if he copied your code.
It wasn't me, it was on the code, i just forgot to edit it '-'
Lol, its all good!
