Dave,

At least you will have to tell how you want to aggregate.

In it simplest form it is only looping through a collection of data and add
the fields that has to be aggregated.

Dave,

Assuming that your Order has a collection of bookings, where in is a value

\\\
dim totalvalue as integer = 0
dim totalpersons as integer = 0
For each bk as booking in MyOrder.BookingCollection
totalvalue = bk.WhateverValue
totalamount = bk.TotalPersons
next
///

I hope this helps,

Cor

Dave,

I showed it you where the bookings are a collection in the order. It can of
course as well with by instance two datatables where the order is the Parent
from the booking or in other words the booking is one of the child of the
Order.

The code stays than almost the same, however you are iterating through the
childs.

To show you one link,

I hope this helps,
