It could be a lot of things. First off, test in the browser, not in some editor's Preview Mode. If there's still a problem, here's what I would suggest -
Use only one copy of jQuery:
Get rid of:
and place that just once in the head before the tags for the fadeslideshow.js and ddsmoothmenu.js scripts.
Then using a text only editor like NotePad, edit the fadeslideshow.js script commenting out the noConflict line like so:
Counterintuitive I know, but noConflict is for use with other script libraries, not when jQuery is the only script library on the page.

Use that version of fadeslisow.js and refresh the page.
If that doesn't fix things, you will need to put up a live demo of the problem and give us a link to it so we can check it out.
