auction skript error

[top05050505]

I'm using money skript with this skript.
but auction skript has error ( can't understand this condition if {auction::start::buyer}'s {money::%player%} >= {auction::start:rice}: )
How can fix it ?
version is JE 1.12.2 / Sk 2.4

options:
    칭호: &6&l[ &f&l경매 &6&l]&f
  
every 1 second:
    {auction::start::time} is set
    remove 1 from {auction::start::time}
    {auction::start::time} <= 0
    if {auction::start::buyer} is set:
        if {auction::start::buyer}'s {money::%player%} >= {auction::start::price}:
            broadcast "{@칭호} &f&l마지막으로 가격을 말한지 30초가 지나 &e&l%{auction::start::buyer}%&f&l님이 아이템을 획득했습니다!"
            remove {auction::start::price} from {auction::start::buyer}'s {money::%player%}
            add {auction::start::price} to {auction::start::starter}'s {money::%player%}
            give {auction::start} to {auction::start::buyer}
        else:
            broadcast "{@칭호} &f&l마지막으로 가격을 말한지 30초가 지났지만 &e&l%{auction::start::buyer}%&f&l님의 돈이 부족해 경매가 무효가 됬습니다!"
    else:
        broadcast "{@칭호} &f&l마지막으로 가격을 말한지 30초가 지났지만 아무도 가격을 말하지않아 경매가 무효가 됬습니다!"
        give {auction::start} to {auction::start::starter}
    delete {auction::start::*}
    delete {auction::start}
