Problem with javascript and cgi

When I write my cgi script with the print qq|  |; thing,
I'd get the following error with my javascript :

CGI ERROR
==========================================
Error Message       : Error loading required libraries.

The script is a rollover script provided by dreamweaver. Its :

function MM_swapImage() { //v2.0
  var i,j=0,objStr,obj,swapArray=new Array,oldArray=document.MM_swapImgData;
  for (i=0; i < (MM_swapImage.arguments.length-2); i+=3) {
    objStr = MM_swapImage.arguments[(navigator.appName == 'Netscape')?i:i+1];
    if ((objStr.indexOf('document.layers[')==0 && document.layers==null) ||
        (objStr.indexOf('document.all[')   ==0 && document.all   ==null))
      objStr = 'document'+objStr.substring(objStr.lastIndexOf('.'),objStr.length);
    obj = eval(objStr);
   if (obj != null) {
      swapArray[j++] = obj;
      swapArray[j++] = (oldArray==null || oldArray[j-1]!=obj)?obj.src:oldArray[j];
      obj.src = MM_swapImage.arguments[i+2];
  }
 }
  document.MM_swapImgData = swapArray; //used for restore
}

The line with swapArray was made the error...


what is wrong with the script?
Hope someone would shed some light into this.
