Zombie event problem please help

[Robbiet6]

For some reason when i turn on the event the object thats set dosent disapear, And the countdown of players dosent occur.
Im guessing its because of this error.............
[Error - GlobalEvent Interface]
data/globalevents/scripts/zombie/onstartup.lua: onStartup
Description:
data/globalevents/scripts/zombie/startup.lua:2: in function attemp to call field 'execute query <a nil value>
stack traceback:
data/globalevents/scripts/zombie/startup.lua:2 in function <data/globalevents/scripts/zombie/onstartup.lua:1>

I realy wana use this Event and the script looks fine to me, so if anybody knows the problem Please can you tell me how to solve it, thanks.

This is the script i am using...
function onStartup()
db.executeQuery("UPDATE `player_storage` SET `value` = 0 WHERE `key` = " .. ZE_isOnZombieArea .. ";")
doSetStorage(ZE_STATUS, 0)
doSetStorage(ZE_PLAYERS_NUMBER, ZE_DEFAULT_NUMBER_OF_PLAYERS)
doSetStorage(ZE_ZOMBIES_TO_SPAWN, 0)
doSetStorage(ZE_ZOMBIES_SPAWNED, 0)
addZombiesEventBlockEnterPosition()
return true
end
