while wait(.5) do
    local children = game.Players:GetChildren()
    for i = 1, #children do
        if children[i].Character ~= nil then
        local hum = children[i].Character.Humanoid
        hum.JumpPower = children[i].leaderstats.Jump.Value/3.12
        if game.Players.LocalPlayer.Character.Humanoid.Jump = true then
            game.Players.LocalPlayer.leaderstats.Jump.Value = game.Players.LocalPlayer.leaderstats.Jump.Value +1
        end
    end
end
