That is a different question.
I assume you have to have the name, date and provider above the sub report.
This means you will have to run the subreport twice and split these items into multiple group footers.
run it once in GFa above the names, return a shared variable, use that to conditinally suppress the next GFb section with the names and dates and a 3rd to re-run the subreport to show results for positive hits.
Or consider moving the names and dates into the subreport and getting them out of the main report.
