Don't just copy paste the format of GetPlayerCountry() and other functions, you have to put the name of string in place of string[]
And also just use 'u' parameter in sscanf, don't use 'd'.
So use this :

PHP код:

CMD:geo(playerid, params[])
{
    new string[128], playa, geo[50], geo2[50], geo3[50];//geo, geo2 and geo3 should be string
    if(sscanf(params, "u", playa))//only 'u' here
    {
        SendClientMessageEx(playerid, COLOR_GREY, "USAGE: /geo [player]");
        return 1;
    }
    if (PlayerInfo[playerid][pAdmin] >= 4)
    {
        if(IsPlayerConnected(playa))
        {
            if(playa != INVALID_PLAYER_ID)
            {
                GetPlayerCountry(playerid, geo);//see changes here
                GetPlayerISP(playerid, geo2);//see changes here
                GetPlayerCity(playerid, geo3);//see changes here
                format(string, sizeof(string), "Looking up %s's GEO.. COUNTRY:%s ISP:%S CITY:%s .", GetPlayerNameEx(playa), geo, geo2, geo3);
                SendClientMessageEx(playerid, COLOR_WHITE, string);
            }
        }
    }
    else
    {
        Invalid_Admin(playerid);
    }
    return 1;
}
