Diaster script not running?

I'm pretty sure it might be because of the spare "" in the disasters. If this is the case this is the script (I haven't tried it yet so it might not work):

disasters = {"Minotaurs!!!", "Zombies"} --Disaster names are case-sensitive and all disaster models must be in the lighting. To add disasters, add ,"..." (example , "Aliens")

getpoints = 100 --Points you will get after Disaster
countdownTime = 1 -- The ammount of time to wait between each disaster.
disasterTime = 100 -- The ammount of time that the disaster will be in the game before it is removed.

countdownMessage = "The next Disaster will occur in %s seconds." -- The message displayed between disasters. %s will be replaced with the number of seconds left.
WdisasterMessage = "Disaster Choosen: %s" -- The message displayed when a disaster occurs. %s will be replaced with the disaster name. Set to nil if you do not want a message
disasterTimeMessage = "The Disasters will stop in %s"
