Gerald,

regarding ths dropdown list:

Using PHP the following would produce a list of records of a specific
field:

* Place in html-section of a php-file *

<select name="ParkList" >
  <option>Select Item</option>
  <option>- - - - - - - - - - - - - - -</option>
  <?php GetDbaseValueList("YourLocation\\YourName.dbf", "YourFieldName")
?>
</select>


* Place anywhere in a php-section *

//
-----------------------------------------------------------------------
// Get the data of a specified column of a .dbf database to a
option-list
//
-----------------------------------------------------------------------
function GetDbaseValueList($dbfname, $NameOfColumn)
{
   if ($db)
       dbase_close($db);
   {
       $db = dbase_open($dbfname, 0);
   }
  $row = dbase_numrecords($db);
  for ($i=1; $i <= $row; $i++) 
  {
     $rec = dbase_get_record_with_names($db,$i);
     $string = trim($rec[$NameOfColumn]);
     echo "<OPTION value=\"$i\">$string</OPTION>\n";
   }
   dbase_close($db);
} //:-



Now zooming to the object should be easy....
