What he means is that if you are running this script locally on your machine, and not through a web server, the environment variables you are trying to use may not be there meaning they are undefined. Try running them through a server and see if you have the same problem.

      Hi All, I am having real problems sorting out the read( ) line, as it keeps bringing up a unititialized error message - I desperately need to fix this ... is there any way ?

      For the $ENV{'QUERY_STRING'} error I enclosed that in a if ($ENV{'QUERY_STRING'}) { <<>> } tag ...Please let me know if there is any way I can fix the read
[reply]
        Yes, do not attempt to read from $ENV{'QUERY_STRING'} if it is not defined. Change that line to: 
        if (defined $ENV{'QUERY_STRING'}) {
    # assign to variable
    # check for login parameter
}

        I'd like to echo davorg's update, though, and suggest you use CGI.pm instead: 
        use CGI;
my $q = CGI->new();

my $age = $q->param('age');
my $login = $q->param('login');

if ($age) {
    # do whatever
}

if ($login) {
    # do whatever
}

        With a mighty WHOMP!, these visible warnings (and several invisible problems probably lurking in your CGI parser) will automagically disappear.
