Count record occurrance report

[je duce]

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?
