module pool- fill all entries

Hi..

  I've developed a module pool screen in which the fields are mandatory and 2 pushbuttons CLEAR and EXIT.

  I've defined EXIT as MODULE EXIT AT EXIT-COMMAND and so as CLEAR.

BUT CLEAR is not working. it is showing error message 'fill in all entries'. i'm are not using any gui status only the screen attributes in which function type is defined as E.

   Please help........
