Uncaught ReferenceError

Question

Hi all,

 

I am adding plug-in for below method and also it is working in one aspx page which refers  from master page. And not working in another aspx page why?

 

It shows following error 

 

Uncaught ReferenceError: $ is not defined(anonymous function)

 

 

<script type="text/javascript">

$(document).ready(function () {

$('.divmarqEMS').marquee(

{

direction: 'left',

allowCss3Support: true,

duration: 10000

});

});

</script>
