    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

      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.

        thanks for your help, I will start changing over to CGI.pm asap ... but is there a fix that will sort the read line for now, as theres a huge ammount of updating to do to change to CGI.pm - while i do that i really need to find a fix for this :(
