[jQuery] Superfish help

[jQuery] Superfish help


Hi there,
I'm a bit of jQuery and Javascript newbie so please bare with me.
I've just implement the Superfish menu plugin, using the package
available at http://users.tpg.com.au/j_birch/plugins/superfish/#download
.
All working fine until I introduced some totally unconnected
Javascript to the mix, I can only assume there is a conflict but I'm
afraid I'm uncertain how to resolve it.
My implementation is:
<style type="text/css">
<!--
@import url(css/menu3/superfish.css);
-->
</style>
    <script type="text/javascript" src="js/jquery-1.2.6.min.js"></script>
    <script type="text/javascript" src="js/hoverIntent.js"></script>
    <script type="text/javascript" src="js/superfish.js"></script>
    <script type="text/javascript" src="js/supersubs.js"></script>
    <script type="text/javascript">
        $(document).ready(function(){
$("ul.sf-menu").supersubs({
minWidth: 12, // minimum width of sub-menus in em
units
maxWidth: 27, // maximum width of sub-menus in em
units
extraWidth: 1 // extra width can ensure lines don't
sometimes turn over
// due to slight rounding differences
and font-family
}).superfish(); // call supersubs first, then superfish, so
that subs are
// not display:none when measuring. Call
before initialising
// containing tabs for same reason.
});
    </script>
Pretty standard stuff I'm sure you'll agree, and as I mentioned this
works as expected.
When I introduce this to the mix:
<script language="javascript" type="text/javascript" src="http://
usr.echoclick2call.com/ini/2717.js"></script><script
language="javascript" type="text/javascript" src="http://
static.echoclick2call.com/scripts/click2call.js"></script>
External scripts that provide additional functionality for the site
the menu fails to render correctly (I lose the default fade effects,
the arrows and a portion of the styling).
Any suggestions?
I was under the impressiong that jQuery was namespaced to avoid
problems like this? Or am I getting confused with another library?
Cheers,
Steve
