<script type="text/javascript">if(window.attachEvent) { window.attachEvent("onload", function() { topNav.intializeMenu('topNav',{select_current: 0, orientation: 1}); }); } else if(window.addEventListener) { window.addEventListener("load", function() { topNav.intializeMenu('topNav',{select_current: 0, orientation: 1}); }, true); }</script>
to:
<script type="text/javascript">if(window.attachEvent) { window.attachEvent("onload", function() { topNav.intializeMenu('topNav',{select_current: 1, orientation: 1}); }); } else if(window.addEventListener) { window.addEventListener("load", function() { topNav.intializeMenu('topNav',{select_current: 1, orientation: 1}); }, true); }</script>
