Jqeury slideshow not working once easing script is added

Hi Folks,

I’m using the wpesp portfolio theme. I’d like to add a lavalamp menu, but when I link up the appropriate javascript files. The slideshow stops sliding.

Here are the two scripts, I can’t see any conflicts or ambiguous names.

I get the following error:

Error: jQuery.easing[jQuery.easing.def] is not a function
Source File: http://www.mharrisweb.co.uk/wordpress/wp-content/themes/wpesp-portfolio/style/scripts/jquery.easing.1.3.js
Line: 46

Which highlights this bit of code:

def: ‘easeOutQuad’,
swing: function (x, t, b, c, d) {
//alert(jQuery.easing.default);
return jQuery.easing[jQuery.easing.def](x, t, b, c, d);

Can anyone tell me why the slideshow doesnt work once the jquery.easing.1.3.js has been added?

All the scrips are here:
