I certainly read your reply and tried it with the session_start as the first line of the php secion. I have since remove the HTML etc. The script appears to work with out error .
I was able to set session vars etc and the script completed with out error and the session vars could be printed out at the end of the script. I then called another php script from my menu frame and was not able to find the _session vars which showed as blanks. I put the session_start() as first line of php block but this still did not make it possible to read the session vars. Do I need to use names sessions or what? Is there some setting that is required in the php.ini or apache to make this work? As I stated at the beigining of the e-mail saga what i want to be able to do is to set global variables which will be available to any php script. In particular i want to ensure that each user has an individual connection to data abse and that this is maintained through out the session. I have set the connection up to use the mysql_pconnect function, but I still need to reconnect in every script which uses the database. I therefore need to be able to caryy the username/password from onepage to the next. Is the start_session and session variables the corect way to do this or is there a better way?
