[LINK] RFI: Inserting Variables in HTML

I want to add to the APF site a feature that leverages off Google 
News, to enable a search for the latest news in the privacy arena. 
Test-page at:

Google's code is buried in all manner of clevernesses that I don't 
want to get involved with.

My requirement is:

Use a form to capture $VARIABLE='KEYED-DATA'
Generate and send:

I can do a form fine.

But (as a dead-parrot programmer - 1967-82), I have two problems:

(1)  I don't know how to reference in HTML a variable whose value is
      set in Javascript.  In the fragments below, the relevant variables
      are:  $searchterm    (what the requestor types in)
            $searchrequest (the URL that's customised and sent to Google)

(2)  I don't know which sequence to put the Javascript and the form in
      (because their syntax is such that each references the other).
      Maybe I need one form to capture the text, and another, with hidden
      variables only, to send the string to Google?

The two fragments I'm playing with are:

<form action="$searchrequest" method="get">
<table border="0" cellpadding="10" cellspacing="0" width="90%">
       <input type="text"   maxlength="800" name="searchterm" size="60" />

<script type="text/javascript">

[I know this is a pretty dumb request;  but The Link Institute is 
both frighteningly competent and fairly tolerant of dumb questions.
