Hello everybody, my problem is OnPlayerStateChange isn't being called properly. Please look in my script

pawn Код:

public OnPlayerStateChange(playerid,newstate,oldstate)
{
    if (newstate == PLAYER_STATE_DRIVER && oldstate == PLAYER_STATE_ONFOOT)
    {
        new veh = GetPlayerVehicleID(playerid);
        if (veh == 425 || veh == 520)
        {
            if (PlayerInfo[playerid][pPermissons] == 0)
            {
                SendClientMessage(playerid,COLOR_WHITE,"You don't have got permissons to use this vehicle!");
                RemovePlayerFromVehicle(playerid);
            }
            else if (PlayerInfo[playerid][pPermissons] > 0)
            {
                SendClientMessage(playerid,COLOR_WHITE,"You have used 1 permisson for using this vehicle !");
                PlayerInfo[playerid][pPermissons]--;
                new string[64], pname[MAX_PLAYER_NAME];
                GetPlayerName(playerid, pname, sizeof(pname));
                format(string, sizeof(string), "%s has used a permisson!", pname);
                print(string);
            }
        }
    }
    return 1;
}

No errors nor warnings when compiled but In Game it doesnt work
