Lua [Spell] Problem!

[XxXHiagoXxX]

I having problems with this script:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TARGETCASTERORTOPMOST, true)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_STUN)
 
local condition = createConditionObject(CONDITION_DRUNK)
setConditionParam(condition, CONDITION_PARAM_TICKS, 6000)
setCombatCondition(combat, condition)

function onCastSpell(cid, var)
local playerpos = getCreaturePosition(cid)
local target = getCreatureTarget(cid)
local trapos = getCreaturePosition(target)
local level = getPlayerLevel(cid)
local damage = (getCreatureMaxHealth(cid)*30)/100

if target == isMonster or isCreature and exhaustion.check(cid, 1002) == false then
exhaustion.set(cid, 1002, 45)
doTeleportThing(cid,trapos)
doCreatureAddHealth(target, -damage)
doCreatureSay(cid, "DIE!", TALKTYPE_ORANGE_1, cid)
return doCombat(cid, combat, var)
else
doPlayerSendTextMessage(cid, 20, "You are exhausted, wait more " ..exhaustion.get(cid, 1002).." second(s) to use Leap Attack again.")
end
end

Let's see, the creature takes the damage but it doesn't show on the screen! The monsters lose life but doesn't show the damage !
The others problem is that i can't put a effect that is showed six times from second to second !
