hi, I am new to CGI an perl. I wrote the following code

$Template = HTML::Template->new(filename => "user_login.html");
$Template->param(USER=>$usr);
$Template->param(PASSWD=>$pwd);
$final = $Template->output();
$q=CGI->new();
print $q->header();
print $q->start_html('user input');
print $q->h1($final);
print $q->end_html();

When i execute the script from my shell it displays the following

Welcome akilesh you have logged in with password root<br>
[download]

But from the browser i get only

Welcome you have logged in with password
[download]

The variables $usr and $pwd are not getting printed to the browser. What could cause this issue Please help me in this
