Ultimate Fade-in slideshow jquery issue

1) Script Title: Ultimate Fade-in slideshow

2) Script URL: http://www.dynamicdrive.com/dynamici...nslideshow.htm

3) Describe problem:
When I insert this piece of code in my page:

Code:

---

<script type="text/javascript" src="fadeslideshow.js">

/***********************************************
* Ultimate Fade In Slideshow v2.0- (c) Dynamic Drive DHTML code library (www.dynamicdrive.com)
* This notice MUST stay intact for legal use
* Visit Dynamic Drive at http://www.dynamicdrive.com/ for this script and 100s more
***********************************************/

</script>

---

All other jQuery script I originally have on my site stop working :( , and produce error: "Uncaught Reference Error: Property '$' of object [objectWindow] is not a function".

What I find out is that I need to include the jQuery library again after this piece of code to fix this issue. It seems that some how the code un-included the jQuery library :confused: and cause the error.
