When I clear the error message, the record is properly appended and all three fields are properly filled in. I have tried eliminating the fields one at a time. If I, for example, only put PKey and nPKey in the INSERT INTO line, I get a Mismatch error. nPKey is the last used PKey + 1--definitely not a mismatch. I have moved the line around and even re-typed it. Same thing--the error follows this line. Everything works fine after I clear the error message, but I can't give the program to my client like this.

See if you don't have an insert trigger in this table.
