jquery issues

Can you tell me how to fix this jquery conflict.

Please check my site: http://newslines.org Ajaxy does not work.

Uncaught TypeError: Object [object Object] has no method 'ajaxyLiveSearch'

However, iot works fine when I add a line to header.php:

script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js">.

BUT, when I do that none of my other jquery items work. Can you tell me how to fix this?
