Doubt about Template Toolkit

logangha has asked for the wisdom of the Perl Monks concerning the following question:

I am using Template Toolkit to generate HTML code. It is used inside a loop. First time (first iteration) works ok, but next it does not do anything. Here it is Perl code

my $headers = HTTP::Headers->new;
$headers->header('Content-Type' =>  'text/html;charset=UTF-8');
print $headers->as_string;
my $template = Template->new({
    INCLUDE_PATH => some path,
    INTERPOLATE => 1,
}) || do {
    my $error = $Template::ERROR;
    my $q = new CGI;
    error($q, "Caught error: " . $error);
};
my $link = "";
foreach my $key (keys %referencesData) {
    $link = $referencesData{$key};
    # Here it is where html is invoked and first iteration works ok, b
+ut next it does not do anything
    $template->process('template.ttml', { link => $link } ) || do {  
        my $error = $template->error();
        my $q = new CGI;
        error($q, "Caught error: " . $error);
    }; 
}

And here it is ttml code

[%# template.ttml %]
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<head>
<TITLE>Some title</TITLE>
<meta http-equiv="refresh" content="$link" />
</head>
<body>
<center>
</center>
<form action="">
</form>
</body>
</html>

As I mentioned, it works ok in first iteration, but next one it seems it does not do anything. What seems to be the trouble?
