I’m trying to create a report that displays the total number of records in a summary section at the bottom of the report.  If I use a field in a report and it’s duplicated many times not sure if these dups count as just a single instance so without testing, I figured I can just use the RecordNumber variable but when I create a New Running Total Field and try to use the RecordNumber in the Field to Summarize it won’t let me.  And if I try to create a formula in Evaluate – use formula section, the OK button stays grayed out.

Bottom line, is there a way to use the RecordNumber as a Running Total Field?
