Q: sessions in a switch block not working

Hello, I'm hoping to get some help with a sessions problem i've ran into. track_vars is enabled and register_globals is off. i'm using PHP 4.0.6 and custom session handlers with ADODB connecting to mysql. at the top: session_start(); if (!isset($HTTP_SESSION_VARS["old_folder"])) { echo "NOT SET<br>\n"; $HTTP_SESSION_VARS["old_folder"] = 1;; } else { echo "IT IS SET: {$HTTP_SESSION_VARS["old_folder"]}<br>\n"; } ----- in the middle of a switch statement: $nasty_folder = $HTTP_GET_VARS["folder"]; $HTTP_SESSION_VARS["old_folder"] = $HTTP_SESSION_VARS["old_folder"] + 444; if (isset($HTTP_SESSION_VARS["old_folder"])) { echo "ADDED 444: {$HTTP_SESSION_VARS["old_folder"]}<br>\n"; } else { echo "FAILED TO ADD<BR>\n"; } --- first time through it prints "NOT SET". second time, without finding my way into the switch it prints "IT IS SET: 1". third time, before going into the case with + 444, it prints "IT IS SET: 1", then i make it into the case and promptly prints "ADDED 444: 445" as the next line. fourth time, i would expect "IT IS SET: 445" without worrying about where i wonder in the switch. can anyone tell me why this isn't working? i do have many lines of code in between but, none deals with HTTP_SESSION_VARS. the only other use i'm making of sessions is setting $uID = $HTTP_SESSION_VARS["uID"] well before the switch statement. $HTTP_SESSION_VARS["uID"] gets set many pages and other PHP scripts before and i just reuse it (as sessions were intended). any help would be greatly appreciated. thanks, joe -- How do i get rid of those words in my screen that are coming from you?
