form cleanup help

[Miller, Gary]

I have one form that doesn't clean-up after itself.  I have found the code
below to be required to hide objects belonging to one form from appearing on
other forms.  Any suggestion as to why this is?

frm = FrmGetActiveForm();
FrmEraseForm( frm);
fldIndex = FrmGetObjectIndex( frm, MyFieldId);
FldEraseField( FrmGetObjectPtr( frm, fldIndex));
