I am writing a search within result page and this page with carry previous submit query string with hidden value. my question is how could I append the previous query string with new submit query string before the full string send to the result page?

and here is a code: 

sub OutputSearchForm {
  my $oldSearch = $queryStringHash{'q'};
  my $searchSelector = CreateSearchSelector();
  my $q = $triplets{"Search"};  # The search query, as returned by Goo
+gle
  
print <<END_OF_HEADER;

<form method=GET action="$scriptName">
 <INPUT TYPE=hidden name=hl value=en>
<table cellpadding=0 cellspacing=0 width="100%" border=0>
 <tr>
  <td width=5>&nbsp;</td>
  <td align=left><font face="arial,sans-serif">
   <input type=hidden name=q value=\"$oldSearch\"> 
   <input type=text name=q size=61 maxlength=256 value=\"$q\">
    $searchSelector
   <nobr>
    <INPUT type=submit name=sa  VALUE="Search&nbsp;within&nbsp;results
+">
   </nobr>
    </font></td>
    <td align=right valign=top></td>
   </tr>
   </table>  
  </form>
END_OF_HEADER
}
