passing field value to a new form

I have a table that allows user to upload a file to a directory on the server and store the filename in the database. This works as expected. What I would like to do, is add a button to the View page that takes the value of the filename field and passes it to a new form (tablename_add.asp) How can I do this?
Thanks!
BTW - ASPRunner is awesome! I'm a Notes/Domino Developer and have a project that needs to be portable as it will be included as a feature set with another application so I had to look at other options. ASP was the best option - but I have never worked with it. ASPRunner got me off to a great start! <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=2501&image=1&table=forumtopics' class='bbc_emoticon' alt=':)' />
