Keycards script error help

[Plav]

So I have a script that makes keycards open doors on right click, but I always get the error
Line 2: (keycard .sk)
event-block is not a world
Line:block data tag "open" of event-block = false:

I was hoping someone could help me fix this

on right click on iron door:
    block data tag "open" of event-block = false:
        cancel event
        block 3 blocks under event-block is lime wool:
            lore of player's tool contains "&1| &9Security I":
                activate event-block
                play sound "block.iron_door.open" at event-block for player
                send "&aAccess GRANTED!"
                wait 2 seconds
                deactivate event-block
                play sound "block.iron_door.close" at event-block
            else:
                play sound "block.note_block.guitar" at pitch 0.8 at event-block for player
                send "&cAccess DENIED! &7(Security I&7)"

I would respectfully suggest rewriting your code in a easier manner.

I would respectfully suggest rewriting your code in a easier manner.

I simplified it to contain just the basic components, hopefully its easier to understand now
