        if (.@nextChoice == 2) break;
        set .@rolls, (.@choice == 1 ? 1 : (.@choice == 2 ? 5 : 10));
        if (.@choice == 3) set .@rolls, .@rolls + 1; // Bonus roll for 10 rolls option
        set Zeny, Zeny - (250000 * (.@rolls - (.@choice == 3 ? 1 : 0))); // Deduct correct Zeny amount
    }

Maybe... because you don't have zeny? can you post your full script?
