You may be running under a Set("decimal")=2 and it may look right, but the jagged decimals may simply be not displayed.

I can not exclude this 52nd bad record (which is in the middle). BTW, I already changed it again today since it looks like the user actaully wanted something different. Originally I was selecting records for the particular Paid date and particular person (I've tried several names and several dates and in practically every case I had one or two bad records with sometimes a very big difference (up to $1 or so). But it turned out that for several people the Paid date was never updated, so I had to run my report for the date range instead and now instead of 52 lines I may see 89 lines with more cases of discrepancy. As I said, I had to examine each such case closely, but I just hadn't time to do so...
