So i have multiple worlds on my server but id like this skript only to work on a world named "prisons" so how can i do that so the skript wouldnt affect the other worlds only work in the prisons world? Heres the skript:

on break of iron ore:
cancel event
set event-block to air
give 1 of iron ingot to player
make console execute "eco give %player% 0.8"

on break of gold ore:
cancel event
set event-block to air
give 1 of gold ingot to player
make console execute "eco give %player% 0.8"

on break of diamond ore:
cancel event
set event-block to air
give 1 of diamond to player
make console execute "eco give %player% 0.8"

on break of emerald ore:
cancel event
set event-block to air
give 1 of emerald to player
make console execute "eco give %player% 0.8"

on break of coal ore:
cancel event
set event-block to air
give 1 of coal to player
make console execute "eco give %player% 0.8"

on break of stone:
cancel event
set event-block to air

 

Where do i add that in the skript? i tried but it says cannot understand this line.
