Im getting a mistake after i add the jquery reducing 1.3 wordpress plugin to my page, i havent even used custom reducing yet but simply loading it stops animated elements working. I am not a jquery expert and so i dont really understand how to debug it but im fairly certain there's a conflict, heres the mistake:

Uncaught TypeError: Property 'undefined' of object #<Object> is not a function

The mistake is triggered whenever you rollover the animated elements, heres the page im focusing on:

should you rollover the hyperlinks &lifier directory you need to see an animated menu open but this is where you're going to get the mistake. I acquired jquery and reducing using the following lines

<script type="text/javascript" src="/wp-content/themes/pegbarAndGrill_01/script/jquery.js"></script>
<script type="text/javascript" src="/wp-content/themes/pegbarAndGrill_01/script/easing.js"></script>

And if i take away the wordpress_mind() and wordpress_footer() functions the conflict disappears. Any idea exactly what the problem may be?

Thank you
