It's hard to say what the problem is, your multiple posts are kindof confusing. I tried to run your nuugmedlum.cgi, but of course I don't have the files you are trying to open. When I substitute a text file to open, the cgi program seems to run OK from the commandline. What happens when you run the program from the commandline, enter your name=value pairs, 1 pair per line, then hit control-d. Turn on warnings too. One thing to look at if your opens are failing is if you have "rights" to do it. Most of the time, a web server is running as "nobody:nogroup"; not you. So you have to make sure the directory you are opening a file in is mode 777. Since you are learning, this would be a good time to learn how to use ptkdb, the perl-tk debugger. You will be able to step thru the program and see what is happening to each variable as you move from 1 sub to another. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
