Actually I should show the last one. 

try

txt += entry.OrderNumber +   + , +   + entry.Produ then the string 
will have all the entries added not replaced.

This is what i have come up with some far... Problem is that it only outputs 
the first entry in the ArrayCollection. So if a client selects more than one
item to buy, when he/she previews their selection, they will only see the first 
entry. Could someone please help me modify this to show all the entries
in the ArrayCollection.

[Bindable]
private var orderColl:ArrayCollection=new ArrayCollection();

/*** Create an object to hold the data ***/
var obj:Object=new Object();

/*** Assign the variables to it ***/
obj.Product=product.text;
obj.Price=price.text;
obj.Qty=1;
obj.OrderNumber=label1.text;

/*** Add the object to the list ***/
orderColl.addItemAt(obj, 0);

Then i have a TextArea component (id=cart) and i try to assign the 
arraycollection to it as text like this

var txt:String;
var n:int=orderColl.length;
for (var i:int=0; i  n; i++)
{
var entry:Object=orderColl.getItemAt(i);
txt = entry.OrderNumber +   + , +   + entry.Product +   + , +   + 
entry.Qty +   + , +   + entry.Price;
}
cart.text = txt.toString();

Either the whole entry is null or one of it's properties. Check which is null, 
and guard your code if null put empty string or whatever you seem fit for it.

That works well. It actually outputs the contents of the arraycollection in the 
textarea component. One very small issue though, it outputs the word NULL 
before the last item in the arraycollection. How do i get rid of that?

Below is the update.

[Bindable]
private var orderColl:ArrayCollection=new ArrayCollection();

/*** Create an object to hold the data ***/
var obj:Object=new Object();

/*** Assign the variables to it ***/
obj.Product=product.text;
obj.Price=price.text;
obj.Qty=1;
obj.OrderNumber=label1.text;

/*** Add the object to the list ***/
orderColl.addItemAt(obj, 0);

Then i have a TextArea component (id=cart) and i try to assign the 
arraycollection to it as text like this

var txt:String;
var n:int=orderColl.length;
for (var i:int=0; i  n; i++)
{
var entry:Object=orderColl.getItemAt(i);
txt += entry.OrderNumber + , ++ entry.Product + , ++ entry.Qty 
++ Unit + ( + s + ) + , ++ $ + entry.Price ++ 
per unit + \n\n;
}
cart.text = txt;
