Pop-Up Menu Code

[aharpro]

I made a navigation in Fireworks MX and saved it as html. It consists a pop-up menu, but the pop-up menu links open in a new window. the navigation page is at http://www.famousfunnies.com/frameleft.htm
The All Comcis Button open up the pop-up menu. Click on one of those links and the page will open in a new window. I want this link to open in the same window. I believe the code for this action is: <script language="JavaScript">
<!--
function mmLoadMenus() {
if (window.mm_menu_0119144243_0) return;
window.mm_menu_0119144243_0 = new Menu("root",129,24,"Arial, Helvetica, sans-serif",18,"#000000","#ffffff","#cccccc","#333333","left","middle",3,0,1000,-5,7,true,false,true,0,true,true);
mm_menu_0119144243_0.addMenuItem("DC&nbsp;Comics","window.open('information/dccomics.html');");
mm_menu_0119144243_0.addMenuItem("Marvel&nbsp;Comics","window.open('information/marvelcomics.html');");
mm_menu_0119144243_0.addMenuItem("Misc.&nbsp;Comics","window.open('information/misccomics.html');");
mm_menu_0119144243_0.bgImageUp="images/mmmenu1_129x24_up.gif";
mm_menu_0119144243_0.bgImageOver="images/mmmenu1_129x24_over.gif";
mm_menu_0119144243_0.hideOnMouseOut=true;
mm_menu_0119144243_0.bgColor='#555555';

mm_menu_0119144243_0.writeMenus();
} // mmLoadMenus()

//-->
</script>


I know absolutely nothing about Javascript. I just need help with this to complete my site. Thanks
