[Pomoc] if provjera

Skripta koju koristim:cyber
Detaljan opis problema:metnuo sam provjeru da ko ima zakaceno policijsko vozilo da ga ne respawna i da mu pise da ne moze odvozit to vozilo i ono se opet respawna i dobije pare za odvoz evo tog dijela:
else if(CP == 14000)
{

if(IsTrailerAttachedToVehicle(vehicleid))
{
SetVehicleToRespawn(GetVehicleTrailer(GetPlayerVehicleID(playerid)));
if(IsACopCar(GetPlayerVehicleID(playerid))) return SendClientMessage(playerid, 0xFFFFFFAA, "Ne mozete odvesti ovo vozilo.");
CP = 0;
DisablePlayerCheckpoint(playerid);
GivePlayerMoney(playerid, 1500);
SendClientMessage(playerid,ZELENA,"(posao) Zaradili ste $1500 za ovaj Automobil!");
SBizzInfo += 1800;
ExtortionSBiz(7, SBizzInfo);
SBizzInfo--;
pOdvoz = 0;
KillTimer(OdvozT);
GetPlayerName(playerid, name, sizeof(name));
}
}
