Oracle Error PLS-00103. How can you check an existing record and update it or insert based on this condition?

Question

I need to check if an entry in the table exists or not from the SELECT statement. If the record exists, upgrade, otherwise create a record in the table. I try, but I get an error PLS-00103.

These are the errors that I get when I run my code in DBVisaulzier:

18:00:09  [DECLARE - 0 row(s), 0.000 secs]  [Error Code: 6550, SQL State: 65000]  ORA-06550: line 2, column 12:

... 6 statement(s) executed, 0 row(s) affected, exec/fetch time: 0.000/0.000 sec  [0 successful, 0 warnings, 6 errors]

Below is my code:

DECLARE a NUMBER;

BEGIN

  SELECT 1 
    INTO a 
    FROM FREC_EMAIL t
   WHERE t.FranchiseNo = '208254846' 
     AND t.ReportID = 1 
     AND t.id = 165;

  IF a=1 THEN

       UPDATE FREC_EMAIL
          SET email = '[e-mail]'
        WHERE FranchiseNo = '208254846' 
          AND ReportID = 1 
          AND ID = 165;

    ELSE

        INSERT INTO FREC_EMAIL
          (FranchiseNo, Email, ReportID)
         VALUES
           ('208254846', '[e-mail]', 1);

    END IF;
END;
