Hey folks -

I'm building a site http://portfolio.stevedolan.com using Dreamweaver CS4 - I just did a browser compatability check and it came back with the following error:

Error - Line 15
Found 1 errors in portfolio.css

Affects: Firefox 1.5, 2.0, 3.0; Internet Explorer 5.0, 5.5, 6.0, 7.0, 8.0b1; Internet Explorer for Macintosh 5.2; Netscape 8.0; Opera 8.0, 9.0; Safari 2.0, 3.0

This is a rollover/preload image script that is a dreamweaver-generated script. I'm wondering why the hell it would generate a script that has an error across all browsers? How can I fix this?

Script is as follows:
<link href="portfolio.css" rel="stylesheet" type="text/css" media="all" />
<script type="text/javascript">
function MM_swapImgRestore() { //v3.0
  var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
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];}}

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];}
