[Scenario]

@ GangsTa[MD]

Okay, I've re-created your script. Please keep in mind I've removed the callbacks and functions that weren't used, or relevant to this system. I usually recommend MySQL, but your going with Dini, which is alright. Please review the attached files, you'll need them to be located in your 'pawno/includes' folder.

pawn Code:

#define FILTERSCRIPT

#include <a_samp>
#include <dini>
#include <dudb>

#pragma unused ret_memcpy

#define COLOR_YELLOW 0xFFFF00
#define COLOR_RED 0xFF0000

#define SERVER_USER_FILE "%s.ini"

    pCash,

{
    gPlayerLogged[playerid] = 0;
    new name[MAX_PLAYER_NAME], file[256];
    GetPlayerName(playerid, name, sizeof(name));
    format(file, sizeof(file), SERVER_USER_FILE, name);
    if (!dini_Exists(file))
