Create summary page for unique values in report

[btj]

I have a report that will show information grouped by 2 fields: ID, Test#

So the grouping will be:
ID
Test#
Category, BuildID, Status, Notes

I have two primary summaries that list in each group footer - number of records per Test# and number of records per ID (including % of total stats). Additionally, I have a Report summary that combines values received in these intra-report summaries.

I want to create additional functionality in these forms by listing the values used in the report (as this will change per user specification).

Example:
List Categories used in this report
List BuildIDs used in this report

I am unsure how to do this or where to begin. If anyone can give me their thoughts, I would greatly appreciate it.

Thanks,
Ben


The length of this report, depending upon User specifications, can be quite long. I
