Java script will not work after creating new page

Question

I am using dreamweaver cs3 and have a java script to rotate a banner in a template.  This script has worked fine in the past when I created pages in Dreamwever.  Now the  script works fine only when I test it in a template but when I try to upload to my ISP the script will no longer work.  At first I thought it was the ISP made changes but the person who sits next to me running the same version of Dreamweaver can create a page and the java works.  The java is placed in a template, tested by viewing in a brower and it works, however once I try to create a new page using the template the scriipt will not work.  To get around this I have the person sitting next to me save my template and then I can create pages.  Also if I save the template with my pc and it updates the pages created by the template the java will no longer work.
This is very frustrating as I cannot create or modify my template on this pc.  What would prevent this from working?

OK - now we are on to something ..... the script on the template only contains:
function randomImages(){
  if(counter == (imgs.length)){
    counter = 0;
MM_swapImage('rotator', '', imgs[counter++]);
  setTimeout('randomImages()', delay);
However when I create a new page from the template with this javascript in it the code changes to:
function randomImages(){
  if(counter == (imgs.length)){
    counter = 0;
MM_swapImage('rotator', '', imgs[counter++]imgs[i]);
function randomImages(){
  if(counter == (imgs.length)){
    counter = 0;
MM_swapImage('rotator', '', imgs[counter++]);
  setTimeout('randomImages()', delay);
