Summon exhaust

[DedicatedOT]

How do you make a lever that summons but with an exhaust of 10 seconds?

I got:

addEvent(doSummonCreature("Metal Guardian",{x=getPlayerPosition(cid).x,y=getPlayerPosition(cid).y,z=getPlayerPosition(cid).z}),10000,cid)

It doesn't seem to work... Says

[20/07/2009 18:30:08] luaAddEvent(). callback parameter should be a function.

local exhausttime = 1 * 60 * 1000 -- 1 minute
local exhaust = createConditionObject(4096)
setConditionParam(exhaust, CONDITION_PARAM_TICKS, exhausttime)

if getCreatureCondition(cid, CONDITION_EXHAUST) == TRUE then
doPlayerSendTextMessage(cid, 21, "Your Exausted. Sad Face no summon for you")
else
summon monster?
