Oracle Forms

I am creating a new list item, and want to populate this with "name" column of my table


I created when-new-form-instance with following code

DECLARE
	
	RG_NAME RECORDGROUP;
	RG_ENAME VARCHAR2(100);
	ndummy number;
	
BEGIN
   	RG_NAME := Find_Group(RG_ENAME);

    IF NOT Id_Null(RG_NAME) THEN 

            Delete_Group(RG_NAME);

      END IF;


	  	RG_NAME := Create_Group_From_Query(RG_ENAME,'SELECT col1, name FROM MYTABLE WHERE ID = 85');


	nDummy := Populate_Group(RG_NAME);


	 Populate_List(':MYTABLE.NAME',RG_NAME);


END;	

I get FRM-41072, I set the required property to be No for my list item, what is the issue, and can I do this manually by creating a new record group also ?
