Compare two cells in a ALV

Question

Hi!!
I'm doing an ALV, and I need to compare two cells. Only one of them could be inform.
I used this code:
      CLASS lcl_event_hadler DEFINITION
CLASS lcl_event_handler DEFINITION.
  PUBLIC SECTION.
    METHODS:
      handle_data_changed
        FOR EVENT data_changed OF cl_gui_alv_grid
            IMPORTING er_data_changed.
ENDCLASS.                    "lcl_event_handler DEFINITION
      CLASS lcl_event_handler IMPLEMENTATION
CLASS lcl_event_handler IMPLEMENTATION.
      METHOD handle_data_changed
  METHOD handle_data_changed.
    PERFORM handle_data_changed USING er_data_changed.
  ENDMETHOD.                    "handle_data_changed
ENDCLASS.                    "lcl_event_handler IMPLEMENTATION
*&      Form  HANDLE_DATA_CHANGED
      text
     -->P_ER_DATA_CHANGED  text
FORM handle_data_changed  USING    ir_data_changed
                                   TYPE REF TO
                                   cl_alv_changed_data_protocol.
  DATA: ls_mod_cell TYPE lvc_s_modi,
        lv_value    TYPE lvc_value,
        lv_value1   TYPE lvc_value.
SORT ir_data_changed->mt_mod_cells." BY row_id.
  LOOP AT ir_data_changed->mt_mod_cells
                           INTO ls_mod_cell
                           WHERE fieldname = 'CELL2'.
    CALL METHOD ir_data_changed->get_cell_value
      EXPORTING
        i_row_id    = ls_mod_cell-row_id
        i_fieldname = 'CELL2'
      IMPORTING
        e_value     = lv_value1.
  ENDLOOP.
  LOOP AT ir_data_changed->mt_mod_cells
                          INTO ls_mod_cell
                          WHERE fieldname = 'CELL1'.
    IF it_prueba-clase IS INITIAL.
      CALL METHOD ir_data_changed->modify_cell
        EXPORTING
          i_row_id    = ls_mod_cell-row_id
          i_fieldname = ls_mod_cell-fieldname
          i_value     = campo_prueba.
    ENDIF.
    CALL METHOD ir_data_changed->get_cell_value
      EXPORTING
        i_row_id    = ls_mod_cell-row_id
        i_fieldname = 'CELL1'
      IMPORTING
        e_value     = lv_value.
    IF lv_value = lv_value1.
      CALL METHOD ir_data_changed->add_protocol_entry
        EXPORTING
          i_msgid     = 'SU'
          i_msgno     = '000'
          i_msgty     = 'E'
          i_msgv1     = 'Only one cell '
          i_fieldname = ls_mod_cell-fieldname
          i_row_id    = ls_mod_cell-row_id.
    ENDIF.
  ENDLOOP.
ENDFORM.                    " HANDLE_DATA_CHANGED
With this code, i can check only one time the cells. If I clear cell2 press enter, and then I write in cell2 again it code doesn't work.
How can i do it with other method?
Thanks in advance

Okay, say the above is my table, how do I compare two cells in a row for two numbers? Say I wanted to find out if row A2 contained a 7 and a 28?
"A2" is an address for a single cell, not a row. Its current content, assuming no empty rows above or empty columns left of what's shown, is "Jan 4, 2011". Perhaps you mean Row 2, or the range B2:G2.
Assuming that you want to know 'if' (or 'how many times') two specific numbers occur in the range of cells from column B to column G in a single row, COUNTIF is the function you want.
Place the two target numbers into cell I1 and J1.
Enter the formula below into I2:
=COUNTIF($B2:$G2,I$1)
Fill the formula right into J2, then fill both down to row 4.
You'll get a count of the occurrences of each number.
If you want only a "Yes" (both numbers appear in the range) or "No" (neither of the numbers appear, or one appears but not the other), use this variation (in I2 or J2):
=IF(AND(COUNTIF($B2:$G2,I$1)>0,COUNTIF($B2:$G2,J$1)>0),"Yes","No")
