When users want to delete a record, they must first find that record in the database. Accordingly, you need a search and a results page to work with the delete page. For instructions on creating a search and a results page, see Building search/results pages (ASP and JSP).
The results page tells the delete page which record to delete by passing it a URL parameter. The next step is to retrieve the record to delete. See Retrieving the record to delete (ASP and JSP).
