runtime error with dhtml js

[awesomebeats]

i'm using dreamweaver and i have a extension that makes the following code for a dhtml layer scroll thing, however, i get an error with line 26, a runtime error. it asks if i want to debug, if i hit refesh everything works. here's the code. the code in red it line 26 that's causing the error.

<script language=&quot;JavaScript&quot;>
<!--
function P7AniMagic(el, x, y, a, b, c, s) { //v2.8 PVII
 var g,elo=el,f=&quot;&quot;,m=false,d=&quot;&quot;;x=parseInt(x);y=parseInt(y);
 var t = 'g.p7Magic = setTimeout(&quot;P7AniMagic(\''+elo+'\','; 
 if ((g=MM_findObj(el))!=null) {d=(document.layers)?g:g.style;}else{return;}
 if (parseInt(s)>0) {eval(t+x+','+y+','+a+','+b+','+c+',0)&quot;,' + s+')');return;}
 var xx=(parseInt(d.left))?parseInt(d.left):0;
 var yy=(parseInt(d.top))?parseInt(d.top):0;
 if(parseInt(c)==1) {x+=xx;y+=yy;m=true;c=0;}
 else if (c==2) {m=false;clearTimeout(g.p7Magic);}
 else {var i=parseInt(a);
  if (eval(g.moved)){clearTimeout(g.p7Magic);}
  if (xx<x){xx+=i;m=true;if(xx>x){xx=x;}}
  if (xx>x){xx-=i;m=true;if(xx<x){xx=x;}}
  if (yy<y){yy+=i;m=true;if(yy>y){yy=y;}}
  if (yy>y){yy-=i;m=true;if(yy<y){yy=y;}}}

if (m){if((parseInt(navigator.appVersion)>4 || navigator.userAgent.indexOf("MSIE&quot>-1)&&

<navigator.userAgent.indexOf(&quot;Opera&quot;)==-1){
    xx+=&quot;px&quot;;yy+=&quot;px&quot;;}
  d.left=xx;d.top=yy;g.moved=true;eval(t+x+','+y+','+a+','+b+','+c+',0)&quot;,'+b+')');
  }else {g.moved=false;}
}
//-->
</script>

any idea why this is happening and what it means

i got a headache trying to follow this code. but assuming your post it correct i'd try changing <navigator.userAgent.indexOf(&quot;Opera&quot==-1){ to (navigator.userAgent.indexOf(&quot;Opera&quot==-1){

yeah the code's a pain but that didn't work cause there already isn't an end ( for that so i had to add another one which was useless. no problem thanx for your help.
