javascripts functions interfere with each other

[alejandro52]

I am using a vertical drop down menu i found on the internet and works great.But when i create a image map with fireworks the javascript it adds interfere with the menus javascript and the menu doesn't work.I am not an expert in javascript and i can't find what causes the problem.Can someone check the code and tell me?Here is the code of the image map

function MM_findObj(n, d) { //v4.01
  var p,i,x;  if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
    d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
  if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
  for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
  if(!x && d.getElementById) x=d.getElementById(n); return x;
}
function MM_swapImage() { //v3.0
  var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
   if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}
function MM_preloadImages() { //v3.0
  var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
    var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
    if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}

And here to code of the menu

function SDMenu(id) {

	};
if (this.markCurrent) {
	var links = this.menu.getElementsByTagName("a");

	}
}
};

		submenu.style.height = newHeight + "px";
	else {

		mainInstance.memorize();
	}
}, 30);
this.collapseOthers(submenu);

};

Load your entire page in FireFox, then post the contents of the error console (Tools -> Error Console) if any. This will help us track down the problem.

It says there is no problem.

I think that the problem is the div and span it uses for the menu to find it.Can someone confirm this?
