Hi,

I have one question regarding iterator. I have one simple list that contain 
three values:
List { id, value, date } and I'm iterating through this list. And I want to 
show in my list a sum for value for every day at the last row that contain that 
date, like this:


id&nbsp;&nbsp;&nbsp; value&nbsp;&nbsp;&nbsp;&nbsp; 
date&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; sum
----------------------------------------------------------
1&nbsp;&nbsp;&nbsp; 10&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 20.5.2008
2&nbsp;&nbsp;&nbsp; 15 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 20.5.2008
3&nbsp;&nbsp;&nbsp; 15&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
20.5.2008&nbsp;&nbsp;&nbsp; 40
4&nbsp;&nbsp;&nbsp; 12&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 21.5.2008
5&nbsp;&nbsp;&nbsp; 15 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
21.5.2008&nbsp;&nbsp;&nbsp; 27
6&nbsp;&nbsp;&nbsp; 12&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 22.5.2008
...

I'm now have done all iterating except this sum column. Do you have any ideas 
how efficent can I do this ?
