Why the need for the _VFP.SetVar?? Can I use just a regular Report Variable?

Thanks

>>I have a weekly report that details the products ordered for each day. The data is sorted by date, customer, product number. There is a footer for customer and date. But in the date footer, I want a count of the number of unique customers for that day. How can I do this?
