2 Day Plus Application Express Developer Guide - error?

Question

Good day !
In "Oracle Database Express Edition 2 Day Plus Application Express Developer Guide" chapter 8 "How to Upload and Download Files in an Application" at the topic "Store the Document in a Custom Table" ( page 8-10, 8-11) is recommended:
6. Under Source, replace the process with the following:
IF ( :P1_FILE_NAME is not null ) THEN
INSERT INTO file_subjects(id,NAME, SUBJECT, BLOB_CONTENT, MIME_TYPE)
SELECT ID,:P1_FILE_NAME,:P1_SUBJECT,blob_content,mime_type
FROM HTMLDB_APPLICATION_FILES WHERE name = :P1_FILE_NAME;
WHERE name = :P1_FILE_NAME;
DELETE from HTMLDB_APPLICATION_FILES WHERE name = :P1_FILE_NAME;
END IF;
7. Scroll up to the top of the page and click Apply Changes.
After this I receive Error Message:
ORA-06550: line 6, column 1: PLS-00103: Encountered the symbol "WHERE" when expecting one of the following: begin case declare else elsif end exit for goto if loop mod null pragma raise return select update while with << close current delete fetch lock insert open rollback savepoint set sql execute commit forall merge pipe
Now I can't find mistake. Please, help me ( if difficulties not so big )

Replace by:IF ( :P1_FILE_NAME is not null ) THEN
INSERT INTO file_subjects(id,NAME, SUBJECT, BLOB_CONTENT, MIME_TYPE)
SELECT ID,:P1_FILE_NAME,:P1_SUBJECT,blob_content,mime_type
FROM HTMLDB_APPLICATION_FILES WHERE name = :P1_FILE_NAME;
DELETE from HTMLDB_APPLICATION_FILES WHERE name = :P1_FILE_NAME;
END IF;The second WHERE clause is superfluous.
