Ok say file.htm had a thing called %!poll!%, and in my script I wanted to replace that with a subroutine, that looks like this. 
sub poll_view {

$sth = $dbh->prepare("SELECT * FROM poll WHERE status = 'active'");
$sth->execute or die $dbh->errstr;
@slog = $sth->fetchrow_array;
print qq~
<table align="center" width="100%" cellpadding="4" cellspacing="0">
 <tr>
  <td class="darktext">
      <font size="2"><b>$slog[1]</b></font>
      <table width="100%" cellpadding="2" cellspacing="2">
~;
  poll_do_it("darktext");
print qq~
      </table>
  </td>
 </tr>
</table>
~;
}

sub poll_do_it {
($ab) = @_;
for($i=2; $i <= 6; $i++) {
  if($slog[$i]) {
    $a = $i + 5;
    print "<tr><td width=\"190\" class=\"$ab\">$slog[$i]</td>
           <td width=\"10\" class=\"$ab\"> $slog[$a]</td>";

    if($slog[$a] eq "0") {
    $fin = "0.00%";
    $num = 0;
    } else {
    $fin = sprintf("%.2f%", ($slog[$a]/$slog[12])*100);
    $num = sprintf("%.0f", ($slog[$a]/$slog[12])*150);
    }

    print "<td width=\"160\">
           <img src=\"images/left.gif\" width=\"2\" height=\"5\"><img 
+src=\"images/poll.gif\" width=\"$num\" height=\"5\"><img src=\"images
+/right.gif\" width=\"2\" height=\"5\"></td>
           <td width=\"10\" class=\"$ab\">$fin</td></tr>";
  }
}
}
