JQuery :: Superfish: No Animation After Loading Superfish.js

I was basically trying to follow several tutorials to get a superfish menu working on my website, but I don't seem to be able to get it to work.I included both the superfish.css and the superfish.js in my website's header; both paths are corrent and point to the designated file.I then included the superfish function in my header like this:

<script> $(document).ready(function(){ $('ul.sf-menu').superfish({
delay: 1000, // one second delay on mouseout
animation: {opacity:'show',height:'show'}, // fade-in and slide-down animation

[code]....

The corresponding <ul> element has the required sf-menu class, but still there are no animations, no fading, no delays, just the plain css functionality provided by the superfish.css.
