Guild Join Npc

[Joker Sama]

Hello my friends. I need an NPC that shows a list of existing guilds, so that players can choose which guild to join without having to be invited by the guild leader.

Mod

script.ccp

// Guild System
BUILDIN_FUNC(guild_join) {
    map_session_data *sd;
    int guild_id = script_getnum(st,2);
    int flag = 0; // Defina o valor apropriado para flag, se necessário

    if( !script_charid2sd( 3, sd ) ){
        script_pushint(st, false);
        return SCRIPT_CMD_FAILURE;
    }

    if( guild_member_added(guild_id, sd->status.account_id, sd->status.char_id, flag) )
        script_pushint(st, true);
    else
        script_pushint(st, false);

    return SCRIPT_CMD_SUCCESS;
}

BUILDIN_DEF(guild_join,"ii"),

Ex: this was my attempt.
But it's not working or showing an error

prontera,152,150,4    script    GuildJoinNPC    100,{
    mes "[Guild Master]";
    mes "Would you like to join our guild?";
    next;
    if (select("Yes:No") == 1) {
        set .@guild_id, 1; // ID of the guild the player will join
        set .@char_id, getcharid(0); // Gets the player character ID

        if (guild_join(.@guild_id, .@char_id)) {
            mes "You are now a member of our guild!";
        } else {
            mes "There was an error trying to add you to the guild.";
        }
    } else {
        mes "Maybe next time.";
    }
    close;
}
