Another solution if you do not want to use running totals...
If you just want a count of how many detail rows per group and your table that is diplaying this detail data has a primary field that uses unduplicated data (e.g. the primary field that is usually a running counter for your table), just use that field, create a Summary on it, summarize as distinct count, summary location would be group1 (assuming you only have one group). This distinct count can be put in your group footer or group header. Note that Running Totals can only be in footers.
