{
public class AccountHolder
{
private var _name:String;
private var _balance:String;
private var _accnum:String;
public function AccountHolder()
{
}
public function get name():String
{
return _name;
}
public function set name(value:String):void
{
_name=value;
}
public function get balance():String
{
return _balance;
}
public function set balance(abalance:String):void
{
_balance=abalance;
}
public function get accnum():String

so here's the problem. the third column in the datagrid is where i'm
having issues.
the third column will specify the balance in the user's bank balance.
If you go through the code you can see that the insertion of entries
into the datagrid works fine. Now suppose there are two entries in the
datagrid and i want to transfer some amount from user1 to user 2 by
specifying the entries in the panel, i.e the amt should be debited
from user1's balance n credited into user2's balance and all the
changes should reflect at the same time. Would this be possible? .
Thanks.
