Hi rpnoble419, Thanks for you sample program. But I still having trouble of getting the values "field". I used TMPL_LOOP NAME to display a list of filenames & checkboxes next to it. This is all done with template & print $template->output. I defined the checkbox inside a form, also a "submit" button.

.......

 <form method="post" action="index.cgi">
 <td><input type="checkbox" name="field" <TMPL_VAR NAME="check"> value
+="<TMPL_VAR NAME = "fn">"></td>
 </form>

when "submit" is click, my main script index.cgi would check check for the command then call a subroutine "download"

sub download {
    my @anything  =  $q->param();
    my $anything_num = @anything;
  
    my @anyfetch = $q->param("field");
    my $anyfetch_num = @anyfetch;

    print "anything_num = $anything_num";
    print "anyfetch_num = $anyfetch_num";
}

both of print give me Zero values, it does not seem like the subroutine is able to fetch the input field from my table html page. I am not sure why. I have the concept, but somehow when applying to coding, it's different story.
