Is it possible to delete a page using a custom_field? I am trying to create an email unsubscribe form using databound and want to know if an email can be deleted using the email address field.

UPDATE: I was able to do it:
1. On form submit I used the email submitted inside the pages tag custom_field to be able to get the email page's id which I set to a variable(email_page_id).
2. I used the email_page_id variable inside the db_delete tag to effectively delete the email from the database. Thank you very much
