[RESOLVED] Crystal Reports 11 - Determining duplicate records?

[blakemckenna]

I have a crystal report that is called from a VB.Net application. The application actually sets the selectionformula (see below)

 
strSelectionCriteria = "{tblBatchHeader.rowID} = " & mRowID & " and " & _
                       "{tblBatchDetail.grossGallons} <> 0 and " & _
                       "{tblBatchDetail.netGallons} <> 0"

crDOC.RecordSelectionFormula = strSelectionCriteria

Duplicate Records are allowed on this report, however, we now need to identify them for easier readability by placing an "*" at the end of the detail line. I would like to be able to do this using formulas but I'm not sure how to do this. There are 3 fields on the report that determine if a record has duplicates. I'm thinking I need to incorporate these 3 fields into some kind of formula. Any ideas?

Thanks in advance,
