Every single HTTP request for a URL (every page the user clicks on, or submits a form, or re-loads) is COMPLETELY independent of the other requests. The only data/values that will "survive" from script to script are the ones you explicitly "save" and "transmit" through GET/POST/COOKIE/SESSION mechanisms. -- Like Music? http://l-i-e.com/artists.htm
