new to JS need help please! :-D

[onesmallstep]

I have been HTML'ng for many many years, however am new to the Java side of it. I'm using a script that works well on another site. Trying to customize it, and having issues.

The previous menu's were to 2 levels, I don't need that, that's what I'm trying to get away from. Logic says just delete the 2 tier and all will be fine, however that just seems to make the whole script not work:

function mmLoadMenus() {
  if (window.mm_menu_0028104603_0) return;
    window.mm_menu_0028104603_0_1 = new Menu("Sales",95,16,"Verdana, Arial, Helvetica, sans-serif",11,"#000000","#ffffff","#ffffff","#00007d","left","middle",3,1,300,-10,5,true,true,true,2,true,true);
    mm_menu_0028104603_0_1.addMenuItem("Fence","window.open('residential.htm', '_parent');");
    mm_menu_0028104603_0_1.addMenuItem("Testing","window.open('commercial.htm', '_parent');");
    mm_menu_0028104603_0_1.addMenuItem("Retail","window.open('retail.htm', '_parent');");
     mm_menu_0028104603_0_1.fontWeight="bold";
     mm_menu_0028104603_0_1.hideOnMouseOut=true;
     mm_menu_0028104603_0_1.menuBorder=1;
     mm_menu_0028104603_0_1.menuLiteBgColor='#cc9933';
     mm_menu_0028104603_0_1.menuBorderBgColor='#33cc33';
     mm_menu_0028104603_0_1.bgColor='#33cc33';
  window.mm_menu_0028104603_0 = new Menu("root",118,16,"Verdana, Arial, Helvetica, sans-serif",11,"#000000","#cc9933","#cc9933","#00007d","left","middle",3,1,300,-10,5,true,true,true,2,true,true);
  mm_menu_0028104603_0.addMenuItem("Free Estimates","window.open('free_estimates.htm', '_parent');");

Thanks!
