Zombie Event Problem

[Wraskly]

NEVERMIND!!! fixed! had to add a return true

NEW ERROR:

The TP doesn't remove when the event does not start because of to few players, Can anyone fix script to remove tp if event doesnt start?

 [17:33:00.568] [Error - GlobalEvents::timer] Couldn't execute event: zombieevent

But everything starts up fine, and when there is not enough players to join, the tp doesnt go away and the event doesnt stop, can someone help me fix this? Heres my globalevents script:

local config = {
    playerCount = 2001, -- Global storage for counting the players left/entered in the event
    zombieCount = 2002, -- Global storage for counting the zombies in the event
    teleportActionId = 2000, -- Action id of the teleport needed for the movement script
    teleportPosition = {x = 1006, y = 998, z = 7, stackpos = 1}, -- Where the teleport will be created
    teleportToPosition = {x = 627, y = 1264, z = 7}, -- Where the teleport will take you
    teleportId = 1387, -- Id of the teleport
    timeToStartEvent = 1, -- Minutes, after these minutes the teleport will be removed and the event will be declared started
    timeBetweenSpawns = 20, -- Seconds between each spawn of zombie
    zombieName = "Fallen zombie", -- Name of the zombie that should be summoned
    playersNeededToStartEvent = 5, -- Players needed before the zombies can spawn.
    
    -- Should be the same as in the creaturescript!
    -- The zombies will spawn randomly inside this area
    fromPosition = {x = 616, y = 1251, z = 7}, -- top left cornor of the playground
    toPosition = {x = 641, y = 1279, z = 7}, -- bottom right cornor of the playground
    }
