Solved Simple lua error

[Glecko]

		doSummonMonster(cid,"Healing Totem")
		summons = getCreatureSummons(cid)
		for i=1,#summons do
			if(getCreatureName(summons[i])=="Healing Totem") then
				local totem = summons[i]
			end
		end
		doSendMagicEffect(getCreaturePosition(totem),CONST_ME_CARNIPHILA)
		setCreatureMaxHealth(totem,getPlayerLevel(cid)*10+150)
		doCreatureAddHealth(totem,getPlayerLevel(cid)*10+50)

I'm getting the error "Creature not found" for getCreaturePosition, setCreatureMaxHealth and doCreatureAddHealth (I guess because totem stays as a nil value).

How is it possible that the creature I just summoned a line ago doesn't make getCreatureName(summons)=="Healing Totem") return true? (The name of the creature ingame is "Healing Totem", too)
I guess I'm missing something really obvious, but I've been looking for hours now and I can't fix it.

Help is very much appreciated

Lua handles local variable declarations as statements. As such, you can write local declarations anywhere you can write a statement. The scope begins after the declaration and goes until the end of the block. The declaration may include an initial assignment, which works the same way as a conventional assignment: Extra values are thrown away; extra variables get nil. As a specific case, if a declaration has no initial assignment, it initializes all its variables with nil.

doSummonMonster(cid,"Healing Totem")
local totem -- nil
for _, m in ipairs(getCreatureSummons(cid)) do
	if (getCreatureName(m) == "Healing Totem") then
		totem = m
		break
	end
end
local hp = getPlayerLevel(cid)*10+150
doSendMagicEffect(getCreaturePosition(totem),CONST_ME_CARNIPHILA)
setCreatureMaxHealth(totem, hp)
doCreatureAddHealth(totem, hp)
-- better one
--[[
for _, m in ipairs(getCreatureSummons(cid)) do
	if (getCreatureName(m) == "Healing Totem") then
		local hp = getPlayerLevel(cid)*10+150
		doSendMagicEffect(getCreaturePosition(m), CONST_ME_CARNIPHILA)
		setCreatureMaxHealth(m, hp)
		doCreatureAddHealth(m, hp)
		break
	end
end
--]]
