Same theory, different implementation. I do same thing to calculate totals of
values like so:
public function calculateTotals():void
{
var data:ArrayCollection = dataProvider;
var i:Number, credit:Number=0, debit:Number=0;
for (i=0;i<data.length;i++){
credit += data[i].credit;
debit += data[i].debit;
}
totalCredit.text = moneyFormatter.format(credit);
totalDebit.text = moneyFormatter.format(debit);
}
Cheers,
Adam

Hey,
This actually doesn't work. Your logic seems to simply count the
number of elements in the arraycollection. I'm trynig to figure out
the number of items in the first element of the collection.
Thanks.
