Report designer, Sub report

[lilgreenpal]

I am working on a report designer and I am trying to put in something like an Access subreport.

So here is kinda what the structure is like
customers
|
-----------

Orders Deliveries

So I want the report to list the customer with its associated orders and then a second detail of the
deliveries This is not the real example it is actually much more complicated. But I think this will suffice
