I tried to remove my relation, delete the record and put it back, but it doesn't seem to work. I only have this problem when i enter 4 records and then delete the last one (4th). I don't have any problems deleting the 3 fisrt records. Here's the code i used to delete in the grid from a command button

Code:
***********************************************
LOCAL liOldSel, lcCodeContract, lcRelationEmployeu, lcRelationContract


SELECT Employeu
lcRelationEmployeu = SET("RELATION")
SET RELATION TO

SELECT Contract
lcRelationContract = SET("RELATION")
SET RELATION TO

DELETE

SELECT Employeu
SET RELATION TO &lcRelationEmployeu

SELECT Contract
SET RELATION TO &lcRelationContract

THIS.PARENT.gridContract.REFRESH()
THIS.PARENT.gridContract.SETFOCUS
*************************************************

Thanks again
