Sure I can help. But first you need to help me. See the first link in my signature about best practices when posting questions. Until you post stuff we can work we are at best shooting in the dark. Post up some ddl and sample according to that article and we can help.

The real challenge is that the way your data is it is going to be very difficult to get this right because you have nothing that ties the details to the header at the moment. Once we have full ddl it will be easier to determine how to proceed.
