Count of a Summary

[jrp]

(edited to add some more info...trying to clarify my problem)

I have a report that has no body - just multiple subsummaries, in a large line item file. Every record in this file is an line item from a timesheet - related to both a staff member (who exists within a department and within a company) and a project.

The Subsummaries are:

Company

Department

Staff Member

Project Name

All of which have an hour total and a cost total, using summary fields.

I want to also include a summary of the count of projects. So a staff person clocks 36 hours, costing $720, and worked on 7 projects total (each project also has a break-down of hours and cost).

But if I create a summary field that is the count of Project Name, I get the number of records (which might be 79) - not the number of Projects.

Can I get a count on a summary?

Many thanks.
