Crystal Reports 10 - how to summarize data across groups and make available to all groups

I have a reports with the following group structure:

Chain - Group 1
Rep - Group 2
Due Date - Group 3

A rep can belong to more than one chain.  I need to know how many chains the rep belonged to at a particular due date to and then make that total it available to a formula in the due date group.

For example, Rep A services Chain 1, Chain 2 and Chain 3 on due date 7/1.  I need to get the value 3 into a formula in the due date group so I can divide a total amount by that number to share costs across all chains the rep serviced in that due date.

You could do this using a subreport and a shared variable.

Your subreport would need to get the total amount by rep.
When you add it to the main report, link on rep id (perhaps other fields as well), and then place the subreport in the Group 2 (Rep) Header.  It would be a good idea to create a second Group Header 2 section and place the subreport in section b.
Your subreport is there just to perform a calculation and to provide that value back to the main report.

The next step would be to create several formulas.

1. @Init - Place it in Group Header 2b - Main Report
shared numbervar rep_amount := 0;

2. @Set - Place it in Subreport Report Footer.
shared numbervar rep_amount := count({table.chainid}); //you may be counting a different field here

Now, you can reference the shared variable in your own calculations in the main report to determin that share costs.
I am nt sure if it can be done easily.  How many Reps?

It might make more sense for this report to group it differently.

Thanks bdreed35, I'll give that a try.
I believe I offered a suitable solution, but the poster never responded back.
