How do I hardcode a dynamic url to an image map?

Question

I am working on a Zip Code search, and have successfully built the search. Now, I need to have the ability to click on an image map of a map, and hardcode an href to a dynamic URL

So for example, the search works well displaying contact information for a zip code in PA. But if I have an image map, I'd like the ability for it to display the same contact information if I click the image map of PA on the map image.

Here is the code I'm using to do the search, and at the bottom is the code I need help with for the image map.

              <form action="search6.php" method="post">
                <p><span class="orange16">Zip Code:</span> 
            <input type="text" name="search_name"> <input type="submit" value="Search" />
            </p>
          </form>

<table width="700" border="0">              

<?php

if (isset($_POST['search_name'])) {
    $search_name = $_POST['search_name'];

        $query = "SELECT * FROM `search4` WHERE `ZipCode` LIKE '%".mysql_real_escape_string($search_name)."%'";
        $query_run = mysql_query($query);


        if (mysql_num_rows($query_run)>=1) {

              }

  }


?>              
</table>  

This is the code for the Image map I need help with. I'd like to use the "CustClassID" data row for my value of lets say "23-LA".

<?php
$query = "SELECT * FROM search4 WHERE CustClassID = {$_GET['CustClassID']}";
echo ("<table width='600' border='0'>  
<tr>
<td align='center'> <img src='images/greymap.png' border='0' usemap='#Map' />
  <map name='Map' id='Map'>
    <area shape='rect' coords='42,21,136,98' href='search6.php?CustClassID=23-LA' />
  </map></td>
</tr>
</table>
");
?>   

Basically, is there another way to get the same results as the search, by clicking on specific areas on the imagemap? Please point me in right direction.
