[EstebanRaffo]

Hello, I´ll need some help to use the DD Tab Menu II on my site (it´s not on line now). The problem is on my web site i´m using this code (from macromedia dreamweaver) when i try to use them together in the same page it gives me this error:

Line: 48
Char: 1
Error: 'null' is null or not null object
Code: 0




MACROMEDIA CODE:

<SCRIPT LANGUAGE="JavaScript" TYPE="text/JavaScript">
<!--
function MM_reloadPage(init) { //reloads the window if Nav4 resized
if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {

else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();
}
MM_reloadPage(true);

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];

if(!x && d.getElementById) x=d.getElementById(n); return x;
}

function MM_changeProp(objName,x,theProp,theValue) { //v6.0
var obj = MM_findObj(objName);
if (obj && (theProp.indexOf("style.")==-1 || obj.style)){
if (theValue == true || theValue == false)
eval("obj."+theProp+"="+theValue);
else eval("obj."+theProp+"='"+theValue+"'");
}
}

function MM_showHideLayers() { //v6.0
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];

obj.visibility=v; }
