Problem with different jQuery versions for multiple jQuery PlugIns

Problem with different jQuery versions for multiple jQuery PlugIns

Hey!

Introducktion: I am new to jQuery, and I don't really know much about JavaScript.
But I am creating a Website, and I relly like the things you can do with jQuery.

Motivation: For my Projekt I want a Slide Menu and a Scrollbar.
I've found some Demos and wanted to embedd them.

The Problem is, they don't use the same jQuery version (i guess).
They work fine single but if I add
  1. <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
to my HTML-Code, my Slidemenu does not work anymore. Parallel to that, if I add:
  1. <script src="http://www.google.com/jsapi"></script>
      <script>google.load("mootools", "1.2.1");</script>   

to my HTML-Code, the Scrollbar does not work anymore.

Hopefully you are familiar with this kind of Problem and can tell me a Soloution where i can keep my Plugins.

Thank you.
