Why are you showing us a "CREATE TABLE guestbook ..." statement? Does this have something to do with the error that you are getting (which you have not shown yet)?

If that is part of the problem, I would guess that you might have configured your DBI connection so that it would die on any sort of sql error, and you are getting an error because a table called "guestbook" already exists in the database.

In order for the "CREATE TABLE" statement not to cause an error, you would either do "DROP TABLE IF EXISTS guestbook" before trying to create it, or else change the "CREATE TABLE" statement to "CREATE TABLE IF NOT EXISTS ..."

For that matter, have you tried using the text from that statement to create the table manually, just to make sure there are no mistakes in the statement?
