Well I got that part :
__ In Template File __

    <tr> 
      <td align="right" valign="baseline">Last Name :</td>
      <td align="left"><input type="text" name="last_name" value = "<t
+mpl_var name=last_name>">
      <tmpl_if err_last_name><br><font color="#FF0000"><strong>Please 
+input your last name</strong></font></tmpl_if>
      </td>
    </tr>

___ In Class ___
....

use Data::FormValidator;
  
  my $Profile = {
    required => [qw(first_name last_name sex city)]
  };
  
  my $results = Data::FormValidator->check($Form,$Profile);
  if($results->has_invalid or $results->has_missing){
    my $output;
    
  foreach my $f ( $results->missing ) {
        $output = $f. " is missing\n<br>";
  }

But the problem is that this doesnt work. It always prints out that one field is mising. And there are other (wich you can see from the profile) ... ?
