The reason is that you reset all the values before even giving the weapon to the player.
Try this:

pawn Код:

CMD:recojerarma(playerid, params[])
{
    new string[128];
    new playername[MAX_PLAYER_NAME];
    new DropObject[MAX_DROP_ITEMS];
    for(new i = 0; i < sizeof(DropInfo); i++)
    {
        if (IsPlayerInRangeOfPoint(playerid, 2.0,DropInfo[i][DropGunPosX],DropInfo[i][DropGunPosY],DropInfo[i][DropGunPosZ]))
        {
            if(GetPlayerVirtualWorld(playerid) == DropInfo[i][DropGunVWorld] && GetPlayerInterior(playerid) == DropInfo[i][DropGunVWorld])
            {
                GetPlayerName(playerid, playername, sizeof(playername));
                DestroyDynamicObject(DropObject[i]);
                GiveZaiatWeapon(playerid,DropInfo[i][DropGunAmmount][0],DropInfo[i][DropGunAmmount][1]);
                DropInfo[i][DropGunPosX] = 0.0;
                DropInfo[i][DropGunPosY] = 0.0;
                DropInfo[i][DropGunPosZ] = 0.0;
                DropInfo[i][DropGunAmmount][0] = 0;
                DropInfo[i][DropGunAmmount][1] = 0;
                format(string, sizeof(string), "* %s recoje el arma del suelo.", RPN(playerid));
                SendNearbyMessage(playerid, 15, string, COLOR_PURPLE, COLOR_PURPLE, COLOR_PURPLE, COLOR_PURPLE, COLOR_PURPLE);
                return 1;
            }
        }
    }
    return 1;
}
