Multi Grand Summaries required

[Stu412]

Hi there

I need to put together a sub summary report from a list of data which includes several 'grand summaries'.  The basic report layout would be something like this, where each record has a sorting field present to identify it as either 'Group 1', 'Group 2' etc...

I'm struggling because, in order to get the Group 1 and Group 2 Summary for example, I need a further layout part against which to hold the calculation - or do I ?  That's the question I'm stuck at and seeing as the same sort of thing occurs further down the page, the report is a non starter at the moment.  

So what I need to do is add together previously summarised results of specific groups and have the results appear in a specific row on the report.

Anybody else have to do this?  Do you need to create a part which is based on a field with nothing in it (which would make the new part appear under each group, which I don't want)?  Very confused here, apologies!

 

Group 1 record

Group 1 record

   Group 1 sub Total

Group 2 Record

Group 2 Record

   Group 2 sub Total

      Group 1 + 2 Grand Summary

Group 3 Record

Group 3 Record

   Group 3 sub Total

      Group 1+2+3 Grand Summary

Group 4 Record

Group 4 Record

      Group 1+2+3+4 Grand Summary

Create a second summary field with the “running”option.
