    leaderstats.Parent = player
    local grass = Instance.new("IntValue")
    grass.Name = "Grass"
    grass.Value = 0
    grass.Parent = leaderstats
    local mgrass = Instance.new("IntValue")
    mgrass.Name = "MaxGrass"
    mgrass.Value = 20
    mgrass.Parent = leaderstats
	local money = Instance.new("IntValue")
	money.Name = "Cash"
	money.Value = 10
	money.Parent = leaderstats
	local xp = Instance.new("IntValue")
	xp.Name = "XP"
	xp.Value = 21
	xp.Parent = leaderstats
	local nxp = Instance.new("IntValue")
	nxp.Name = "NXP"
	nxp.Value = 20
	nxp.Parent = leaderstats
	local rank = Instance.new("IntValue")
	rank.Name = "Rank"
	rank.Value = 1
	rank.Parent = leaderstats
xp.Changed:connect(function()OnLevelUP(xp,nxp,mgrass,rank,cash)
end)end
