Setting option selection in Jump Menus

How do I set the option selected in a jumpmenu when using a dwt template to create the menu on multiple pages?

Currently. when I change the page, it always restores back to the initial option (page 1), even when I have 'restore' set to 0. What I want it to do is stay at what I selected, even after it changes the page (ie. when I select page 2 I want the jum menu to indicate Page 2, even after it refreshes to Page 2).

Here's the code:

FIRST: THE TEMPLATE USED TO CREATE THE PAGES:

<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <!-- TemplateBeginEditable name="doctitle" -->
        <title>Main Template</title>
    <!-- TemplateEndEditable -->

    <SCRIPT language="JavaScript" SRC="jumpmenuscript.js"></SCRIPT>
</head>

<body>
<form name="form" id="form">
  <select name="jumpMenu" id="jumpMenu">
    <option value="../Try/page_1.html">page_1</option>
    <option value="../Try/page_2.html">page_2</option>
  </select>
  <input type="button" name="go_button" id= "go_button" value="Go"    onclick="MM_jumpMenuGo('jumpMenu','parent',0)" />

</form>

<!-- TemplateBeginEditable name="Page Identifier" -->
<!-- TemplateEndEditable -->
</body>
</html>

NEXT, AN EXAMPLE PAGE (BOTH PAGES ARE IDENTICAL, EXCEPT FOR THE HEADING)

<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <!-- InstanceBeginEditable name="doctitle" -->
        <title>Main Template</title>
    <!-- InstanceEndEditable -->

    <SCRIPT language="JavaScript" SRC="jumpmenuscript.js"></SCRIPT>
</head>

<body>
<form name="form" id="form">
  <select name="jumpMenu" id="jumpMenu">
    <option value="../Try/page_1.html">page_1</option>
    <option value="../Try/page_2.html">page_2</option>
  </select>
  <input type="button" name="go_button" id= "go_button" value="Go" onclick="MM_jumpMenuGo('jumpMenu','parent',0)" />

</form>

<!-- InstanceBeginEditable name="Page Identifier" -->
<h1>This is Page 1</h1>
<!-- InstanceEndEditable -->
</body>
<!-- InstanceEnd --></html>

FINALLY, THE JAVASCRIPT: // JavaScript Document

function MM_jumpMenuGo(objId,targ,restore){ //v9.0
  var selObj = null;  with (document) { 
  if (getElementById) selObj = getElementById(objId);
  if (selObj) eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
  if (restore) selObj.selectedIndex=0; }
}
