Error 94' - Invalid Use of Null

2 New Member
I restored a SQL database on another system diffrent from the system used for development and invoke the VB object code. The two interfaced but navigating withing the forms was not possible. Error 94 was reported. I also noted that data shown in combo boxes were duplicated. "Key column information is insufficient or incorrect - Too many rows were affected by update" message is also reported when the Next button is clicked. Meanwhile, the version on the original system works perfectly ok. Could any one offer me any help? Thanks in advance.
