If you refresh the form the $_REQUEST array will essentially be empty for those vraibles that would be passed from form to process.

OK I'm confused. I want to set a variable with a form. How do I do that? I guess I need to put it in the url? I did a mail form & that worked by putting stuff in the $POST and when it refreshed to the same mail page, I grabbed the stuff back out of that (at least that's what I thought I was doing. Maybe I just put the new value in the url with the action property of the form and forget about the $POST part. I guess I don't know how that worked for the mail script.
