What I meant is before the reported line to use printf to print the value of "carid". But.. just for the sake of debugging, you might as well separate each condition and add print messages:

pawn Код:

if (carid != -1)
{
    print("carid != -1");
    if (Car_IsOwner(playerid, carid)) printf("Car_IsOwner(%i, %i)", playerid, carid);
    else if (CoreVehicles[vehicleid][vehTemporary]) printf("CoreVehicles[%i][vehTemporary]", vehicleid);
    ...
}

Continue with the rest.
