Make sure to add this callback somewhere:

pawn Код:

OnPlayerCommandPerformed(playerid, cmdtext[], success)
{
if(success == 0)
return SendClientMessage(playerid,0xFF000AA,"Put your Error Message over here if invalid command."); // Optional.
return 1;
}

Also, converting the tune command into ZCMD:

pawn Код:

CMD:tune(playerid, params[])
{
        new playerstate = GetPlayerState(playerid);
        if(playerstate == PLAYER_STATE_DRIVER)
    if(IsPlayerInRangeOfPoint(playerid, 10.0, 1256.05, -1469.17, 13.61))
        {
        ShowPlayerDialog(playerid, DIALOG_TYPE_MAIN, DIALOG_STYLE_LIST, "Tuning Garage", "Paint Jobs\nColors\nHoods\nVents\nLights\nExhausts\nFront Bumpers\nRear Bumpers\nRoofs\nSpoilers\nSide Skirts\nBullbars\nWheels\nCar Stereo\nHydraulics\nNitrous Oxide\nRepair Car", "Enter", "Close");
        return 1;
        }
        else
        {
           return SendClientMessage(playerid, COLOR_RED, "SERVER: You need to be in a Tuning garage.");     }
        }
        return 1;
}

Make sure it's out of any callback [CMD:tune].
