Running Total

I want to get a running total of the number of rows in a report. I have a formula that is COUNT([field name]), which returns a value of 1. To get the running total value, do I have to first create a var text query on the field I am counting?

var text QUERY //var text QUERY = "{fid#.}";

Is the Running Total formula: SumValues(GetRecords($QUERY),fid#)
