Trigger not working

Question

Good Day !
Hi ,
Scenario , I have a oracle form i'm loading the data from text file to the form(non - database block), it have two columns "CODE" and "Verify".
The data will be populated in the column "CODE", Once the complete data is loaded in the Form, Each value in the "CODE" column is verified with database lookup table, if the value in the "Code" column exist in the database then Corresponding "Verify" will have value as YES,
otherwise it will be NO.
My issue is the file is getting populated using webutil, but the corresponding value in "Verify" not populated
My script given below... At When- button - pressed...
DECLARE
   txtfile    text_io.file_type;
   linebuf    VARCHAR2 (1800);
   filename   VARCHAR2 (30);
   ret        NUMBER;
   count_pl   NUMBER;
BEGIN
   count_pl := 1;
   filename := webutil_file.file_selection_dialog ('D:\');
   IF (filename IS NOT NULL)
   THEN
      txtfile := text_io.fopen (filename, 'r');
      text_io.get_line (txtfile, linebuf);
      LOOP
         ret := 0;
         :count_plmn := count_pl;
         :form_code := linebuf;
         text_io.get_line (txtfile, linebuf);
         NEXT_RECORD;
         count_pl := count_pl + 1;
         text_io.new_line;
         EXIT WHEN linebuf IS NULL;
      END LOOP;
   END IF;
   GO_BLOCK ('block5');
   FIRST_RECORD;
   LOOP
      IF :roam_plmn_code IS NOT NULL
      THEN
         SELECT COUNT (*)
           INTO ret
           FROM lookup
          WHEREcode = :form_code;
         IF ret = 0
         THEN
            :valid_roam := 'N';
         ELSE
            :valid_roam := 'Y';
         END IF;
      END IF;
      EXIT WHEN :SYSTEM.LAST_RECORD = 'TRUE';
      NEXT_RECORD;
   END LOOP;
END;can any one help ASAP , Thanks in Advance.

Hi,
Is the below code same as written in your form or is there some typo error:
SELECT COUNT (*)
           INTO ret
           FROM lookup
          WHEREcode = :form_code;I can't find a space between WHERE and code. Not sure, if it is a typo.
Another thing, is form_code a data item in block5?
Hope it helps.
