Hi,
try the following code...and change the <.....>  according to your program..Do the same thing for the second screen field also.
If you face same problem then please let me know.
module display_f4help input.
  call function 'F4IF_FIELD_VALUE_REQUEST'
    exporting
      tabname           = '<tablename>'
      fieldname         = '<fieldname>'
      dynpprog          = sy-cprog
      dynpnr            = sy-dynnr
      dynprofield       = '<screen-field name>'
    exceptions
      field_not_found   = 1
      no_help_for_field = 2
      inconsistent_help = 3
      no_values_found   = 4
      others            = 5.
  if sy-subrc <> 0.
    message id sy-msgid type 'S' number sy-msgno
    with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  endif.                                     " IF sy-subrc <> 0.
