using BK ver 6.5.7- While comparing two databases with 79,000 names that I knew only had a few differences I got many errors reported. I then made a copy of my master file and did a compare and still got many errors, all involve persons with multiple marriages. The left screen has a person with 2nd or 3rd spouse showing but right screen is showing same person but with the first spouse so they don't match. If I manually change the right screen to the correct spouse they then match. I believe the problem only occurs if second spouse has lower bk number than first spouse. Maybe something for John to check. Joe
