Solved Creating and Deleting Worlds with MultiVerse?

[acai]

Hello! I'm making a minigame, but creating worlds with Multiverse doesn't seem to work. Any help?
My code (quite long):

#--------------------
on damage:
damage cause is fall:
cancel event
command /mbadmin [<text>] [<text>]:
permission: gumble.mineblock.admin
trigger:
if arg-1 is "spec":
make player execute "vanish"
make player execute "tp arg-2"


command /mineblock [<text>]:
trigger:
if arg-1 is "create":
execute console command "/mvc %player% -t flat"
give 1 of wooden axe to player
else:
if arg-1 is "delete":
execute console command "/mvdelete %player%"
make console execute "mvconfirm"
on mine:
if {minedblocks.%player%} is not set:
set {minedblocks.%player%} to 0
add 1 to {minedblocks.%player%}
if {minedblocks.%player%} is 1000:
set {minedblocks.%player%} to 0
execute console command "/eco give %player% 10000000"
#--------------------

Copy-Paste decided to remove my indentation.
