Thanks.
The files are, respectively, in these locations:
C:\wamp\www\sbl\wp-includes\js\jquery\jquery.js
C:\wamp\www\sbl\wp-content\themes\sbl3\scripts\jcarousellite.js
Surely if the first one works then so should the second!?
Could WAMP, Windows or WordPress prevent access to the latter file like can happen on a server if your permissions are wrong?
