>>>Yes, I checked that. The key to this is that on about half the lines it works fine. So if something were checked that shouldn't be or somthing like that, it seems to me that it wouldn't work at all. What's wrong has to be something that is getting changed from line to line. But what? That's what has me stumped.

I meant using a pencil. Work thru the data by hand and make a list of the desired results, then make a list of what the VFP Report is producing. Calculate the differences, divide backwards, multiply forwards, and try to find out where the numbers are coming from. Put ALL the variables on the report, if you have them in group bands, copy them to the detail band.

Once again, good luck, its a pita, but I don't have a better answer.
