Printing only if records greater than one

I am trying to create a report based on a table of about 10,000 records to display records with duplicate street addresses. I created a report with a grouping on the street address field and only want to print records where there is more than one record showing a particular address. The report will enable us to pick out records where "customers" may be attempting fraud by using a particular false address. At any rate, I am unsure how to do it. I want to put code in the detail "onPrint" section that will make the report skip those records with single addresses. Or perhaps there is another way to do it, perhaps in a query? Thanks for your help.

Never mind. I figured it out. I used a query to base the report on.
