How to perform substitution : thisform.objects in FOR EACH

I try

mFormObject = 'THISFORM.Objects'

FOR EACH oControl IN &mformObject
IF INLIST(UPPER(oControl.baseClass),'TEXTBOX','EDITBOX','COMBOBOX','CHECKBOX')
BINDEVENT(oControl,'InteractiveChange',THISFORM,'mEnableSave')
ENDIF
ENDFOR


But get error message : nesting error.


TIA.
