Hi i am trying to implement sessions in my web application. I have been using a number of different web resources including cspan to help me. However i keep stumbling upon errors. The code i am using is shown below 
if($ENV{REQUEST_METHOD} eq 'POST')
{
    $q = new CGI;

    $username = $q->param('user_name');
    $pword = $q->param('pwd');

}

my( $session, $query, $cookie, $name, $cgi);

#Create a new session
$session = new CGI::Session(undef, undef, {Directory=>'./tmp/sessions'
+});

#Allow cgi-session read the cookie at the next request
$cookie = $query->cookie( -name => $session->name,
                          -value => $session->id );
print $query->header( -cookie=>$cookie);

#Store the username in the session
$name = $cgi->param($username);
$session->param($username, $name);

#Check if the username and password match
#Do rest of code

I keep getting the error "Can't call method "cookie" on an undefined value" I am not sure if the place that i put the session in my code effects how it runs? I have it stored after the params are read in from the form submitted by the user, but before checks are done to validate those params submitted by the user. Can anybody tell me why this is happening, and where I am going wrong. I would greatly appreciate any help!
