Change
$oCar=$objCar[1];
to
$oCar=$aCar[1];
Your not in the foreach loop anymore so $objCar is left as equal to
$aCar[2] at that point. Your statement says in essence
$oCar=$aCar[2][1]; I assume $aCar[2][1] is invalid. Then change
if($oCar->$this->m_sColor=="Blue")
to
if($oCar->m_sColor=="Blue)
unless your $this variable has as a property name in it at that point.
If it does you could do
if ($oCar->$$this->m_sColor=="Blue")
where $this == the name of an internal object...
I don't really see why if($aCar[1]->m_sColor=="Blue") couldn't work
there as instead of all that.
