[Fisx]

hmm can someone say me why my script don't work?

while (true) do
AMOUNT = 0
for i = CREATURES_LOW, CREATURES_HIGH do
local CREATURE = Creature.GetFromIndex(i)
if (Creature:isMonster() and Creature:Name(Larva) and CREATURE:isOnScreen() and CREATURE:isAlive()) then
AMOUNT = AMOUNT+1
end
end
if (AMOUNT >= 5) then
if (Self.CanCastSpell("utamo vita") and Self.Mana() >= 50) then
Self.Say("utamo vita")
wait(195000, 200000)
end
end
wait(100)
end
