Hello, I recently used some javascript code to utilize a drop down menu, it works great in IE, but the alignment is off in Firefox and more importantly, the menu's do not show up when moused over. Can someone please help me? I posted the functions and their calls below. Thanks!

<script language="JavaScript">
<!--
function MM_findObj(n, d) { //v3.0
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); return x;
}

function MM_showHideLayers() { //v3.0
var i,p,v,obj,args=MM_showHideLayers.arguments;
for (i=0; i<(args.length-2); i+=3) if ((obj=MM_findObj(args[i]))!=null) { v=args[i+2];
if (obj.style) { obj=obj.style; v=(v=='show')?'visible':(v='hide')?'hidden':v; }
obj.visibility=v; }
}

frames array is IE only.

function MM_findObj(n, d) { //v3.0
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); return x;
}

Thanks! do you know of any quick fixes for this? I didnt write the code so I am somewhat limited in knowledge at this point

try substituting

parent.document.getElementsByTagName('iframe')
or
parent.document.getElementsByTagName('frame')

depending if frames or iframes are used, for

parent.frames
