If else clause in Oracle database

I wish to add a new record in my oracle database and update it if it already exists. I am using If else clause to achieve this . Below is my code :

DECLARE
  any_rows_found number;
BEGIN
  select count(*)
  into   any_rows_found
  from   reports
  where  report_id=27;
  IF(any_rows_found > 1)
  THEN
  UPDATE reports set
        TITLE = 'Check user entered keywords have valid resource link',
       CATEGORY = 'zData checks',
       DISPLAY_ORDER= 9120,
       QUERY ='...',
       CONTENT_SEQ=1,
       DELD=0,
       ADMIN_ID=1,
       DATE_UPD = to_timestamp('05-FEB-15 01.44.53.753311000 PM','DD-MON-RR HH.MI.SS.FF AM') 
      WHERE REPORT_ID = 27;
  ELSE
    INSERT INTO reports (REPORT_ID,TITLE,CATEGORY,DISPLAY_ORDER,QUERY,DESCRIPTION,CONTENT_SEQ,DELD,ADMIN_ID,DATE_UPD)
VALUES (27,
        'Check user entered keywords have valid resource link',
        'zData checks',
        9120,
        '...',
        1,
        0,
        1,
        to_timestamp('05-FEB-15 01.44.53.753311000 PM','DD-MON-RR HH.MI.SS.FF AM'));
  END IF;

This throws follosing error as seen :

PLS-00103: Encountered the symbol "end-of-file" when expecting one of the following:

( begin case declare end exception exit for goto if loop mod
   null pragma raise return select update while with
   <an identifier> <a double-quoted delimited-identifier>
   <a bind variable> << continue close current delete fetch lock
   insert open rollback savepoint set sql execute commit forall
   merge pipe purge
06550. 00000 -  "line %s, column %s:\n%s"
*Cause:    Usually a PL/SQL compilation error.

Where am I goig wrong ? Please help. Thank you.
