I always appreciate you going above and beyond. Thank you.
I did a test submission and the page is not redirecting. I fixed it and the email did come through.
In the test, I chose tomorrow as the date. When I went into the admin section, on the events_details and events_update pages, the date and the end_date fields are both displaying as 1969-12-31. I checked the phpmyadmin database, just to be sure it isn't a visual formatting thing in the admin and it shows there incorrectly too.
In the update page, I did what you said about the checkbox and it is not updating the authorize field in the database.
Sorry to be a bother...
