Rapid Respawn OTS Check1/Check2 HELP

Hi,

I am playing on an OT server and they have just recently introducted rapid respawn. That means all the time I have monsters around me that I try to kill wasting SDS/POTS at the same time. The walker doesn't move forward as the character is busy killing the monsters.

I would like to request a script that will be on all the time, and whenever I will have X pots and X sds it will go to label by itself.!

Thats what I tried to do myself but doesnt work for some reason, any help?

local ManaID = 23373 --- Which mana potions are you using?
local MinMana = 100 --- How many mana potions until you leave the hunt.
local MaxMana = 600 --- How many mana potions you begin the hunt with.
local HealthID = 3155 --- Which health potions are you using?
local MinHealth = 200 --- How many health potions until you leave the hunt.
local MaxHealth = 1300 --- How many health potions you begin the hunt with.

if (Self.ItemCount(ManaID) < MaxMana) or (Self.ItemCount(HealthID) < MaxHealth) then
setWalkerEnabled(true)
gotoLabel("Refill")
end
