You did real good especially for a first timer on such a thing! You've gotten yourself into just a little bit of a problem because you used BETWEEN instead of the more effective classic [font="Courier New"]Invoice_Date >= start of this month and Invoice_Date < start of next month[/font], but we'll hammer that out. I'm still at work. I'll wittle on this tonight.
