Can't I use this type of code?

I used this code.
But skript said "Can't understand this condition/effect".
Can't I use this type of code?

format slot 27 of player with charcoal named "목탄 5개" with lore "&6팔고싶어! : 1 에메" to close then run [
        if player has 5 charcoal:
            give player 1 emerald
            remove 1 charcoal from player
        else:
            send "{@prefix} 자원이 부족하네요! 저는 언제든지 기다리고 있으니 나중에 또 오세요!" to player]

I think you can do sth like this:

... to close then run [myFunction(player)]

function myFunction(p: player):
    if {_p} has 5 charcoal:
    #etc...

I tried that code. But I faced this error.

The function 'myFunction' does not exist.

Change to vanilla..:

#....
    if {다나잡화점 메뉴.%player%} is "sell":
        open chest with 5 rows named "광물은 언제든지 환영이라구요!" to player
        set slot 10 of current inventory of player to coal named "석탄 1개" with lore "구매가 : 1 에메"
        #....

on inventory click:
    if name of current inventory of player is"광물은 언제든지 환영이라구요!":
        if clicked slot is 10:
            if clicked item is coal:
                execute console command "/give %player% emerald 1"
                execute console command "/clear %player%
