lvl = script.Parent.Up.LVL
local LVL = player.leaderstats.LVL
tool = script.Parent
exp = lvl.Value
max = 2
val = 20


tool.Activated:connect(function()
	if LVL.Value == max then
up = true
LVL.Value = "MAX!"	

elseif up ==	false then
	lvl.Value = lvl.Value + 1
up = true
wait(0.5)
up = false
if lvl.Value >= val then
	LVL.Value = LVL.Value + 1
	lvl.Value = 0
	val = val + 10
	end
end
