So I finally found the solution to the problem. It was in the validate.js function. I corrected the error by calling the outside functions of validate.js and jquerry:
script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.4.4.min.js"
script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.7/jquery.validate.min.js"
