So i made this a long time ago, but at this time its not working. Im using skript purely vanilla without addons. Can someone help me with this? thanks 
options:
permission: Irondoor.Open
on right click:
if player has permission "Irondoor.Open":
if event-block is iron door:
if player can build at location of event-block:
toggle event-block
if event-block is iron trapdoor:
if player can build at location of event-block:
toggle event-block
the error is
Can't understand this condition: 'player can build at location of event-block'
So i want to do so people can right click on the iron door, so it opens without a button and so on. It should only be possible for people who has access to the specific area
