Well, I tried your suggestions, and they worked, kind of. Now what I get is a running total.
I guess I should let you know what the objective is. This is a report showing the profit margin of all items sold for the last month, grouped by salesman first, and second by sales orders, giving me two group headers. The report is designed to subtotal each sales order, and then subtotal all sales orders by salesman, with a grand total at the end.
The subtotals I'm having problems with are the sales orders; the salesman's totals seem to work okay, but when I copy the format, it REALLY doesn't work. I would appreciate ANY help I could get. My bosses are very frustrated right now!
