I'm trying to create a report which in effect will count the number of sales for each salesperson has over a given period. Each sale invoice denotes the date and the specific salesperson for that invoice. I need the report to list each unique salesperson and the number of invoice records they appear in. The sales person varies from period to period. Presently I can use a list to sub summarize by sales person and then add the invoice. This is not very elegant nor practical when the number of invoice can get exceedingly large. Any thoughts?

Did additional research in the forums and found a resolve in Post# 163453 by "comment". The example provides the proof of concept necessary to solve my needs. Thanks "comment"
