Hi, i have two forms.

Form A:
- Dataenvironment: tables CV and HERITAGE
- Form A calls Form B
- Has the picbtns class

Form B:
- Dataenvironment: tables HERITAGE
- I'm adding a record with this code:

APPEND BLANK
WITH thisform
	replace padre WITH .combo1.value
	replace madre WITH .combo2.value
	replace hijo WITH fils
ENDWITH 
thisform.Release

But after i return to the Form A and try to move through the records with the pictbtns class, it displays this error 5 consecutives times:

FAILED TO ADD/UPDATE RECORD(S) BECAUSE OF NON UNIQUENESS

How can i solve this problem?
Thx
