Javascript Internet Explorer

Hi i have this script which works well with all browsers except IE. you can see the functions when you click on the male /female. It toggles between the DIV’s on selection.
Please advice how do i get it to work in IE

<html>
<head>
<title>Example</title>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js">
</script>

    <script type="text/javascript">
    //<![CDATA[
    $(document).ready(function() {

        $('.toggle').show();
        $('.gender').click( function() {
		$('.toggle').hide();
          var target = this.id + '_content';
          // Use ID-selectors to toggle a single element.
          $('#' + target).toggle();
          // Use class-selectors to toggle groups of elements.
          $('.' + target).toggle();
          $('.toggle.always').toggle();
        });
        $('#toggle_everything').click( function() { $('.toggle').toggle(); });
    });
    //]]></script>
