If it doesn't see the file, issue a META refresh to itself say every 20 seconds or so with a simple "processing data" screen. If the file exists, then delete that file and continue on with the normal processing you have in proces.php</p> <p>-Greg</p> Wed, 31 May 2006 15:32:11 +0000 Greg K comment 1201105 at https://www.webmaster-forums.net
